Hello Instructor:

I followed your instructions and I completed all projects. This is an example of the led light experiment.

It worked fine. 

All projects worked fine except controlling the servo motor through potentiometer project and the speaker project.

Failure reason for servo motor project is probably because I had the wrong header pins or wrong servomotor (and/or I didn't place stuff in right places; I will try again later).

Failure for speaker project: I ordered the wrong speaker, it's quite large with no wires yours had wires so I had no idea what to do with it or if I can put jumper wires to make it work, but it doesn't seem like there is option to put in wires in it; I will order another speaker and try this experiment again.

I learned a lot and got a lot of familiarity with electronics. This is my first electronics course. 

Thank you for this class.
