  • 555 ASTABLE (TONE GENERATOR) PROJECT KIT

This kit is perfect for studying the use of a 555 timer in its astable mode, where it produces a square wave output. The frequency of which is adjustable via the variable resistor. 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.
