Pomodoro timer script, that randomly turns an LED off after a minute - until none are left. It starts in green and turns red over time. This is written for a tiny ESP32-C3 board that features a 5x5 RGB LED matrix. Now cooldown time integrated.

davedarko / candle.ino

Created December 9, 2018 20:21

	/*
	Program Description: This program reads a light detecting resistor thru an internal ADC and stores the value,
	after scaling it, to eeprom. This ADC value is sent to a PWM channel with attached led. This is essentially a data logger
	for light and replay by LED. If, if you aim the LDR at a flickering candle during its recording phase, you have a flickering
	led candle.

	A circuit description and other details can be found at http://petemills.blogspot.com
