HANDY TIMER KIT

Click to enlarge

  • A versatile project for groups of students,
  • Ideal for Key Stage 3-4,
  • Complete kit of components and high quality PCB,
  • Bulk discount options available.

The timer works in intervals of 30 seconds. Every push of the button advances the timer 30 seconds and an LED. Pause after setting, then press again to cancel timing.

It beeps every 30 seconds as the timer counts down, then plays a brief tune when the timing has finished.

Circuit goes to sleep when not in use so no switch is needed and the battery lasts for months.

Power supply requires one 3v 2032 button cell, (sold separately) that fits in a holder on the PCB meaning there are no wires needed.

The kit contains a PCB and all components needed to construct a complete circuit.

Kits sold as single, 10x pack and 50x pack.
