Steady hand game project kit (with latch)

The board has a buzzer that sounds momentarily when the loop makes contact with the wire. It also has an LED, which latches on when the buzzer sounds via the use of a thyristor. It then remains on so that even the briefest contact of the loop with the wire can be indicated. A push button is used to reset the LED.

This kit contains (per kit):

• 1 x PP3 clip lead
• 1 x 3AA battery holder
• 1 x piezo buzzer
• 1 x 220ohm resistor
• 1 x 10Kohm resistor
• 1 x 10nF capacitor
• 1 x thyristor 2N5061
• 1 x 5mm red LED
• 1 x push to make switch
• 0.5m connecting wire
• 1 x steady hand PCB
• Heat shrink
• Tinned copper wire and flexible connecting wire

The cables are supplied on reels with the remaining parts being individually bagged.

PCB dimensions: 53mm x 25mm.

Requires x3 AA batteries, available separately.
