AVR vs PIC: The case of the candle
https://www.electronics-lab.com/avr-vs-pic-case-candle/
A self-igniting candle implemented using AVR and PIC microcontrollers. This project has two variations, one using an ATTiny25, the other using a PIC12LF1822. In a series of minimalistic devices, this electronic candle periodically measures ambient light levels. Once it detects nightfall, it self-ignites and burns for three hours, flickering as a candle does. The flicker […]

Dark Sensitive Switch – LED Light
https://www.electronics-lab.com/dark-sensitive-switch-led-light/
Dark activated LED light is a simple project which operates a LED when the light falling on the LDR goes below a set point. The circuit is built using LM393 comparator, LDR as light sensor, preset (potentiometer) for sensitivity adjustment, transistor to drive the LED. The project can also be considered for use in energy […]
