Beautiful little DIY kit. A heart-shaped circuit board with 22 red LEDs, changing the brightness of the LEDs up and down.
The speed of the effect can be adjusted with a little trimmer potentiometer.
You don’t need to be an engineer to assemble this kit. Basic knowledge of electronic components and circuits is all it takes.
All the parts and their positions are clearly printed on the circuit board.
Make sure you install electrolytic capacitor, LEDs, Transistors and the IC in the right direction as shown on the PCB.
The kit needs a power supply of 4-6V DC.
