Summary

This circuit involves an Arduino UNO microcontroller interfacing with a KY-026 Flame Sensor, a 5V relay, a Piezo Buzzer, and a WS2815 LED Strip. The circuit is powered by two 18650 Li-ion batteries. The Arduino UNO reads the flame sensor's output and controls the relay and buzzer accordingly. The relay, in turn, controls the power to the LED strip.

Documented Code

Arduino UNO 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 UNO. The setup() function is where you initialize your components, and the loop() function is where you place the code that needs to run continuously.
