Forward and Backward DC Motor circuit

Forward and Backward DC Motor circuit using Arduino and LCD in proteus

In this article we will learn how to make Forward and Backward DC Motor circuit using Arduino and LCD in proteus.
In the last post we will learn how to make Relay ON & OFF circuit in proteus using Arduino nano and LCD display. You can visit our website,
I hope you appreciate my work, let’s discuss about today’s project.

Components:

1. Arduino nano
2. LCD display
3. DC motor
4. Relay (12v)
5. Diod (4007)
6. Transistor (BC547)
7. Resistor (10k)
8. Jumper wires
