Design And Construction Of A Triple Mode Tone Generator
Overview
ABSTRACT
This work is on a triple mode tone generator circuit that generates three different tones. It can use it as a call bell, burglar alarm or any other security alarm.
The circuit operates off a 12V battery. At the heart of the circuit is an LM556 dual timer IC having two separate LM555 timers built into it. The first timer is configured as an oscillator with a wide frequency range. The second timer is triggered by the output of the first timer. The circuit produces three sounds depending on the position of the rotary switch (S1). S1 is a single-pole, three-way switch.
