This is an implementation of the famous electronic game "Simon says" (aka Senso) with a LPC810 - ARM Cortex M0+ in DIP8 case. The minimalistic design needs only 18 parts for the realisation. It's esay possible to built your own Simon on a breadboard.
We provide also a DIY kit with pcb and THT parts for beginners including the pre programmed LPC810 - see
