A power supply of 4-12V is required.
The PCB is 48mm in diameter.
This little project demonstrates the function of the decade-counter IC CD4017.
The print on the PCB shows all the components on one side. This makes sense because the PCB is only single-sided (no plated through-holes). But as you can see in the image gallery, we mounted the microphone and the LEDs from the backside with about a 5mm distance to the PCB. This gives the module a way more attractive look, but it also is a little more challenging since it requires soldering underneath the LEDs and the microphone.
