The Edu Blinking LED Soldering Kit is an educational PCB (or printed circuit board) that demonstrates electronic circuits and the components used.
After soldering the electronic components, just add a 9V battery (not included) and the two red LEDs will start blinking. You can also adjust the blinking frequency of each LED using two potentiometers. The kit can be used for a variety of purposes, including plastic model building and light effects.
