This kit is perfect for studying the use of a 555 timer in its astable mode, where it produces a square wave output.

The board has a choice of two outputs. The logic output can be used to drive another IC or a speaker can be connected so the tone is heard (e.g. a door bell). The push button switch connects to the reset line such that the IC is only active when the button is pressed.

This kit contains:

  • 1 x 555 timer IC 
  • 1 x 8 pin IC holder 
  • 1 x 3.3Kohm resistor 
  • 1 x 10Kohm resistor 
  • 1 x 47Kohm potentiometer
  • 2 x 10nF ceramic capacitors 
  • 1 x BC547 NPN transistor 
  • 1 x push to make switch 
  • 1 x PP3 clip lead 
  • 1 x 3AA battery holder 0.5m connecting wire 
  • 1 x tone generator PCB
  • PCB dimensions: 40mm x 40mm.
  • Requires x3 AA batteries and depending upon desired use a speaker, both available separately.
