From the project
Solder practice PCB for kids
I designed this PCB to teach my 6 years old son soldering and some electronics basics. The cutout on top fits a standard ID card clip, so the PCB can be worn as some kind of brooch if desired.
The resistors need to be calculated according to the LED color and the desired current. Red LEDs running at 10mA would be 150R.
