Read carefully:
This is a completed electronic project but could be fun and/or interesting for kids with supervision.
It switches a relay - in this case the included battery light, on and off by the clap of a hand.
It just needs a 12v battery or low voltage DC supply.
Although the circuit board is exposed it could be fitted to a box.
If powered correctly via a battery or low voltage 12v DC power supply it is harmless in its current state.
Fully working and tested.
Ask for more info if required.
