Description
The FK1901 “Like Symbol” Flasher alternately flashes between 2 different groups of LEDs.
The LEDs are arranged in a green set and a red set, which simulate a “LIKE” emoji (thumbs up).
The flash rate can be adjusted by turning the potentiometer.
This is a very easy-build introduction to basic electronics.
