Week 10: Transistors and Motors

Reading Notes

Important!

Mark all the components and put them back in the right bag after used. The transistors and the voltage regulators look very similar. Got them mixed up many times.

Using Transistor to Control DC Motor

The motor I got is an SG90 micro servo motor. Unlike the one shown in the lab, it has 3 wires, including one PWM wire. The motor Jane got is also called SG90 motor, but hers only has a positive and a negative wire. Not sure if it could work as the two wires one.

Controlling a DC motor / Stepper Motor

Still waiting for the H bridge to come! I Will update once I got it.
