Lab: Using a Transistor to Control High Current Loads with an Arduino
It worked! (However, Alina told me that she also used sg90 DC motor, but hers has three wire (contains a pwm wire) and hers didn't work at all.)
Lab: DC Motor Control Using an H-Bridge
This lab didn't work. I think my circuit was the same as the schematic. But it just didn't work. (As far as I noticed many other students faced the same situation😂)
Lab: Controlling a Stepper Motor With an H-Bridge
I changed the value of stepsPerRevolution from 512 to 2048, then the motor could rotate 360 degree.
