Description 555 Timer Astable Tone Generator Kit - Kitronik
This kit is ideal for students who need to use a 555 timer in its astable mode. In this mode a square wave output is produced. The frequency of this is adjustable via the variable resistor. The board has a choice of two outputs. The logic output can be used to drive another IC. For example, a speaker can be connected so that the tone is audible. This way you can make a doorbell, for example.
The push button switch is connected to the reset line. This makes the IC active only when the button is pressed.
