Control a DC Motor with arduino

This video tutorial explains how to use a transistor with an Arduino to control a DC motor. It begins with a review of a basic LED circuit and demonstrates how the same code can be adapted to control a motor. The tutorial covers the use of an N-channel MOSFET transistor to manage the higher current required by motors, compared to LEDs. It provides detailed instructions on connecting the motor and power supply, emphasizing the importance of a common ground and avoiding short circuits. The video also explores controlling motor speed using a potentiometer and touches on advanced topics like electrical noise and voltage spikes.
