Relay Module Project

The Relay Module project demonstrates how to control a relay using an Arduino Mega. The relay can be used to control high-power devices like lights, fans, or other electronic devices by switching them on or off.

Components Needed

• Arduino Mega
• Relay Module
• Jumper Wires
• Power Supply for the device controlled by the relay
• Breadboard
• Power Supply

Instructions

Code Upload:

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Mega.

Testing:

Open the Serial Monitor in the Arduino IDE (set to 9600 baud) to monitor the output.

Observe the relay turning on and off every 2 seconds, controlling the connected device.
