ArduCandle

The ArduCandle is a simple project for a candle flickering effect using an Arduino Nano (ESP32), LEDs, and a button.

Step 1: Installation

The development kit used for this project is a Arduino Nano ESP32, and the documentation refers to that module. However, any board should do the trick.

Step 2: Assemble the circuit

The circuit is very simple:

1. connect the two LEDs to the ground with 220 Ohm resistors;

2. connect the anodes to pins 2 and 3 of the Arduino Nano;

3. connect the button to ground using a 10 kOhm resistor;

4. connect the grounded side of the button to pin 7 of the Arduino Nano;

5. (optional) for better deboucing, insert a 2 uF capacitor between the connection to the board and ground.
