This project has been designed to introduce the important concept of astable timers and pulse-width modulation using a 555 timer astable circuit.

This Economy version contains a basic set of components and the PCB.

This circuit is very important as it features heavily in KS4 curriculums. The range of projects has been designed to have more than one possible outcome and therefore more than one application.


  • Frequency can be varied by adjusting the two variable resistors
  • Battery-powered
  • Clear silkscreen text has been used to make construction simpler
  • Professional double-sided PCB pre-drilled with silkscreen and solder-resist

Please see the Technical Details tab for more information.

Empty PCBs are available separately, order code 70-9036

Suitable for Key Stages 2, 3 & 4 (ages 7 to 16)

Comprehensive teacher notes are available here.

14 November 2017 Question by: Derrick | Product code: 70-6017
Q. Is the PCB single sided or does it have tracks both sides and plated through holes?
A. Hi Derrick, thank you for your question. The plating is on both sides but only designed to be soldered on one.
