This is Ashraf from educational engineering team. 2. 2 Simulating Arduino Boards on the Web Trim: Hello and welcome to this new lesson in which we are going to start by simulating an Arduino board. Now once you go to the platform, you will see a list of projects that you can start with. Green or mega ESP 32, Arduino nano pico, and micro Python on the SP theta2. Now, we will start with the first one which is Arduino Uno. And to go to this platform, all what you need to do is to write this word W0 wi.com using your browser. And your browser will do. So. Let's get started by clicking on the Arduino on. Now here we have the Arduino Uno board. As you can see. Here, we have our coding area. And as you can see, we have this pattern where you can toggle between full screen to build the grid, turn it on or off. If you have something to do with spaces between components, you can zoom in or out, or you can use your keyboard to zoom in and out. All. You can simply click F to fit this to the screen. You can also enter full screen mode or click on Help to get help regarding anything. Now, we also have the blast button, which is the add a new part button. This is a list of parts that you can add. And for this we will use the LCD. Now. We have to answer D is also the 60 by two. And LCD 60 by two I2C. We will use the I2C since it has less wires, only four wires. So click once and drag it and drop it here. Now, you can zoom in and out using your mouse, crawl as you can see. And let's connect these. We have VCC, which you need to connect to. As you can see, it's already marking the pins to which you can connect your Vcc two, which is the fivefold. We also have the ground and the coloring is automatic. Now it's also helping you by marking the ground pen. Now we have the SDA and SCL. We will connect a CL to A5 and we'll connect SDA to A4. Now as you can see, this, a wire that you can click on ones to change the color. So you can make it yellow to make things different. And you can also move it using these circles. Now you can move it from here, or you can move it from here. Again, you can zoom in and out using the keyboard or the mouse scroll. You can make it fit screen by pressing F. And it will fit, as you can see. Again, ground vcc as the ACL, now as d and the CL, if you don't know I2C, you should look it up. It's a communication protocol that allows you to transfer data using only two wires, data wire anticlockwise. Now, to program our code, what you need to do here is simply add the LCD library. So let's do this here. Hash include liquid, and you can see that we have autocomplete feature. Now we need the liquid crystal I2C library. Once done, you need to set the pins, right? Liquid star underscore. I see. Then LCD, which is the object. And in here, you need to write 0 x to seven, which is the address follow-up LCD. And you need to write 24. Now. Now 24 here means 20 column by four rows. Now, the one that we have here is 16 by two. Now once you are done with this step, you can move on to the next step, which is basically inside the void setup. We need to add the LCD initialize. So LCD that initialize. After that you need to turn on the backlight. Lcd backlight. And the last step is LCD to set cursor so that you can set the cursor was a sham. So see you are SLR. And we'll set it to 1. First column 0, okay? Now the last step is to print something LCD that print hello. Word, occasional, okay, hello, because we don't have a lot of space. Now, once done, you can go inside the loop as well and move the cursor to another location. So Street LCDs and make it 81. And we can supply anything. You can type LCD rent. Inside here you can provide video and team. Now, list this things out. Now once you are done with the code, if it doesn't have any syntax errors, you can simply hit the play button. Now if everything is working correctly, you should see this on your LCD. Now, you interest him is not showing. So I want to go back the five gold on number five here. So stop play again. Now we have drawn here at the Orange team. Hello world. Now, let's explain, let's explain again what happened. We connected the LCD using I2C. And in here. First we added the liquid crystal I2C library. Then we moved on and created LCD with the I2C address and the size of the LCD. We initialize the LCD, we turned on the backlight. We set the cursor position to the beginning, and then we printed hello world and inside the setup function. After that, inside the void loop, we move the cursor to the second line, the fifth column, and we printed a two inch team. As you can see here. You can change this. You can print something else, like LCD. And you can print the middle is divide it by 1 thousand. Now let's see how this will go. Okay? Now as you can see, as Arduino's on, it will keep counting the time and print it here, which is something beautiful. Now, this is the first example using an Arduino board and an LCD. I didn't want to turn it on and off because everyone knows how to do that. And this is a simple example as well. Now you can add other components. As you can see, you can add RTC, you can adopt GB LED. You can have seven segments are PIR, motion sensor, temperature sensor, and any other sensor. 3. 3 Simulating ESP32 Boards on the Web Trim: Welcome to this new lesson in which we are going to simulate ESP Thursday toolbar. Now, you need to go back to the platform. Click on ESP 32. Now let's get going. This is our ESP 32. I prefer to turn the grid on. Now here is the board. We need to connect a resistor and an LED. So click the plus sign. Had an LED, drag it here. Now we also need that as this resistor. This is just so that's what I was talking about. Now if you click here, you can see the description for this item which is the resistor. Now let's go back to that previous page. Here we are. Now. Now to retain the resistor, simply select it and risk are. Now on your keyboard. I had to change the anguish, sorry. Now, just out on your keyboard so that you can easily rotate that. Now, let's connect it. First. We need to connect the ground. Here we have anode and cathode. So once you click on the cathode, you can simply connect it to the ground here. Now click ones, change the color to black of this drug, drug and connect the other pin to, let's say d two. Now you can change the color again. Now here's a trick. Once you have connected that is a store, you need to change the resistor value to 220. And in order to do this, you need to go to that diagram, the json, and look for the walk. We change the value to 220. And as you can see, as you are changing the value, the colors are changing as well. So let's change this to 1 thousand. As you can see. Now, bring it back to 220. And now we have that I value. Go back to the sketch. Again. This is done using the diagram, the json. And by looking for the component and the type section, then change the value and this attribute. That's it. Go back to the sketch. And now we have the sketch. Now, this will print. Hello. Yes, we talked to on the serial monitor. What we need to do is to define the LED. So define LED. And the value will be two, since we are using D2 here. Now, the next step is going here. Black pen mode, which is the function that we use to set up in as input and output and select out the lead, which has been number two, will be treated as outward. Since this LED is basically an output, go back to the loop. Now inside that all we need to turn this layer on and off. Digitalwrite. Led. And high. Either delay. Off, let's say 500 milliseconds. Then digital light again. Lids, low. Delay, again, 500 milliseconds. Now let's move this. Won't need it. Once you are done, you have connected everything correctly. And here we have the lead, that is this torque and our ESP theta2. You can't run the simulation. As you can see, the built and let this turning on and off. And the outside lid that's connected to D2 is also turning on and off. This is how you can easily turn and LED on and off using ESP theta2 on this platform. Now, let's make things a little bit harder by adding an input. So if the button or an input button, if the button is clicked to turn it on, if not, it will turn it off. To do this, we need another pen. So define button. And let's make it bend for, which is this term. Now, the next step is setting this as output. So pinMode button and select output. The button will be the input. Now, after doing this, we need to use a digital read function. So baton states equal digital. We need to read the status of that button. Now once we read the button Status, we will store it inside the button status integer, and it will either be one or 0. Now, if else, Let's do this. Veteran status equal equal one. We need to turn that in on. Otherwise, we will turn it off. So this is our code now it's up and ready. Let's review this. We have an LED and a button connected to pin number two. And for the eyelid is an output, that button is an input. We are reading the button state and storing it inside the button state variable. Now, vitamin state equal equal one. Then we will turn it on and wait for 500 milliseconds. Else, if the buttons set is equal, 0 means the button's not pressed, and it will turn that off. Now, in here, we need to start adding components so you can look for the most part one and simply place it here. Let's zoom out. Now this pattern, as you can see, we have 1234. So we have these two pens, one lift and right, and we have two left and two, right? So this is, we can connect it directly to pin number four. And the other part, we can connect it directly to, let's say five volts or 3.3 volts. It's up to you this by connecting this to three months, three months. Now, let's test things out. Now the button, this button connection is wrong. You have to connect, pull up or pull down to check if it is working or not. Now, this is giving us and always on-state. So let's fix this. Here. We need to make sure that button state is initialized, appears and make it equal 0 out here. Outside of this area. Now we will move from here. Now, in this case, the button is directly taking five volts, so we need to add a resistor. Here. Rotate it. It is. Now this is a still be connected to three volts. And it says, and here we have this button connected. Now. You have to fix the button connection. Let's delete this. Now. This is connected to five volts or 3.3 volts through this resistor. And the other pin must be connected to ground. Now the output will be taken from button 12, left. So drag it and place it here. Now here we have the resistor connected to 11, right? And 11 lift is connected to ground. One to lift is connected to default. But one input. Now, turn it on. Few clicked once and waited. Now it's sitting on, sometimes it takes some time to, let's say, process that codes because this is an online platform. But here it is. Now. It's off. Now. It will turn on. And now it will turn off. Now, this is how you can connect a button and an LED. We tried output and input with ESP 32 and this example, I hope that everything is clear. Thanks for watching this lesson. If you have any questions I'm here to help. This is Ashraf. 4. 4 Simulating Raspberry Pi Pico on the Web Trim: Welcome to this new lesson in which we are going to show you how to simulate Raspberry Pi beagle. Now pKa is the ball supported for now. More to come later. Now click on last failure by Pico. And you will see this. Now. As you can see, this is the last petabyte vehicle. And you can see the pens and everything. And the left side here, you can see a symbol C code that you can use on this raspberry pi p. Now this is serial. Again. We have cylinder to print new line. Hello raspberry white people. Now, you can run this in the simulated environment depend. You will see this, this hello Last favored by people. As you can see here. Now you can change this text with anything you want. You can do occasional engineering team. And you can't run it again. To see that as long as you can see educational engineering team. Now, this is a C code. It's not a Python code. And you can use all of our C functions inside this peak or Raspberry Pi B. As you can see, you can interface with general purpose input, output pins. And you can communicate to this ball using the same duration you usually use with Arduino. For instance. Let's try to turn this LED on and off. Now let's explain how you can turn this layer on and off. First step, as usual, is to define a hash, define LED. And it's been about 25. Now in hand. You need to use that pen wound lent out. And in here, you need to use this to light lids, high and delay. Milliseconds. Digitalwrite again. And ED low. Gla, 500 milliseconds again. Now once you are done, click Save and click on. As you can see that it does turning on and off. Now you can connect an external lead with a 220 ohm resistor. And it will also turn this LED on and off. Now this is done using C. So you can go back and use the Raspberry Pi people with micro Python. So let's go back again. You can simply click here micro Python on pi pico. And you will see here that we have a Python code. Now, this Python code will allow you to use Python to turn this on and off all to read any digital estate of these pens. And you can do this by running the following code. So let's start with typing clear font, machine and poor pen. Now and part-time asset that we need to set that it led equal. And this spring will be five for number 25, pen dots out. Now, to turn this LED on and off, you can simply write led the token. And you can add a time delay, 0.5. You can leave the print hello pico, or you can delete it. Now let's test things out and see if it will work or not. All we need to do any modifications. Now, let's run. Now as you can see, we are having our problem. So let's see what's happening here. Now the issue that happened is that we did turn it on, but we don't have an infinite loop so that it is turning on only ones. If you concentrated here, you will see that it turning on ones then off. To fix this, all that you need to do is go here, right spline tool and move these using the Tab button. Now, click Run, and then it will turn on and off. This is a simple Python code that we use to tear the built-in LED, which has been 25 on and off using this simulated platform. I hope that everything is clear now. Thanks for watching this lesson. 5. 5 Save and Share your Simulated Projects Trim: Welcome to this new lesson in which I'm going to show you a few more tracks.
