Tone Generator using 555 TIMER IC hand made on GPB (General Purpose Board)

Introduction

• Description: The following circuit is a tone generator using 555 timer IC. Feature: Simple circuitry, 5V supply voltage, battery powered, vibrating signal output. Component: 555 timer IC, resistor, capacitor, speaker

  The 555 timer chip is an integrated circuit which is used to create a vibrating signal. It can be operated with a 5 volt power supply or with a 9v battery, and can be made to produce a wide range of frequencies. The frequency it generates is inversely proportional to the resistance and capacitance placed in the circuit.

  A circuit diagram for a typical tone generator is shown above. Construct your tone generator on a breadboard. If you need more detail, you can look at a breadboard diagram or photograph. Attach a headphone jack where speaker leads are indicated, so you can listen to the tone which this circuit produces.

   

  The heart of the tone generator is an integrated circuit chip; the 555 timer. Other resistors and capacitors are need to control the frequency of vibrations produced. The list of parts suggests five volts, so the LVPS (set at 5 volts) will work well.
