In this project I developed a system that allows Remote Control of the speed and direction of a DC Motor. I used an Arduino Nano, and components from the Elegoo Kit.

Components

• Arduino UNO or Nano
• Breadboard or PCB
• Motor Driver L239 chip
• DC motor from Elegoo kit
• IR remote transceiver from Elegoo kit
• Wires/Jumper Cables

Libraries

• IRremote.h

Schematic

Process

The main purpose of this project is to allow Remote Control of the speed and direction of a DC Motor. The initial task is to map button pushes on the Infrared Remote Control to useful functions in the Arduino. The remote control receiver is connected as follows: R on Remote to 5V, G on Remote to Ground, and Y on the Remote to Arduino Digital Pin 9. A Motor Driver L239 Chip is used to drive the DC motor. Its connections can be seen in the schematic.
