Circuit Documentation

Summary

This circuit integrates an Arduino UNO microcontroller with a 1-Channel Relay, an RCWL-0516 Microwave Radar Motion Sensor Module, an LED Rope Light, and an AC Supply. The Arduino UNO is used as the central processing unit to control the relay based on the input from the motion sensor. The relay switches an AC circuit that powers the LED Rope Light. The motion sensor detects movement and sends a signal to the Arduino, which then activates the relay to turn on the light.

Additional Notes

• The code provided for the Arduino UNO is a template and does not contain any functional code. It needs to be populated with the logic to read the motion sensor output and control the relay accordingly.
• The documentation file for the code is empty and should be filled with relevant information as the code is developed.

This documentation provides an overview of the circuit and its components, along with the wiring details and the initial code setup for the Arduino UNO. Further development and testing are required to ensure the circuit functions as intended.
