Circuit Diagram
Assembly
The driver needs 12v power to work. For this project we have used 8 1.5v batteries. The driver has a 5v outlet which is suitable to power the Arduino Nano.
The connection of the 2 wires motor with L298N can be in any order ( to one motor outlet). The order decides the clockwise direction for the motor.
