Throughout this ENPH 259 lab, a servo-motor controller was constructed, which could accurately control the speed of a brushed motor. I learned how several components operated, including a digital-to-analog converter using a resistor ladder, the motor measurement using an LED and photo-resistor, as well as how the counter, latch, and DAC work together with a couple of op-amps to control the speed of the motor.

Here is my full write-up for this lab:
