Fun for young and old like doctor bibber or the hot wire! A player has to lead the non-insulated loop (in the picture the end of the brown wire) from one end to the other end as quickly as possible and, above all, error-free without bumping into the bent silver wire. Because here the circuit is closed, a soft hum from the buzzer signals the error acoustically just like the budding red led. This corresponds to an error and it is the next player's turn.
contact is closed, in that case the red led is on
Especially on New Year's Eve, when you are somewhat clouded by alcohol, you can use this skill game to get an indication of your ability to drive.
not perfect, but we had fun recording
Apart from the led, which must be oriented the right way round (the long leg is plus), the resistance and the buzzer can simply be plugged into the breadboard. We can do without an on/off-switch: there is no contact with the wire from the loop, no current flows.
Have a safe journey at all times and a happy new year.
