Circuit Documentation

Summary

This circuit consists of multiple LEDs of different colors, resistors, a Hall sensor, an IR receiver, an Arduino Nano microcontroller, a LiPo battery, a rocker switch, and an electrolytic capacitor. The circuit is designed to control the LEDs and read inputs from the Hall sensor and IR receiver using the Arduino Nano. The power is supplied by a 3.7V LiPo battery, and the circuit can be turned on or off using the rocker switch.

Code Documentation

Arduino Nano Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino Nano. The setup() function is where you initialize your components and settings, and it runs once when the microcontroller is powered on or reset. The loop() function contains the main code that runs repeatedly. You can add your specific logic to control the LEDs, read the Hall sensor, and process the IR receiver signals within these functions.
