HARDWARE REQUIRED

PIN DESCRIPTION

555 TIMER IC

Pin

Name

Purpose

1

GND

Ground reference voltage, low level (0 V)

2

TRIG

The OUT pin goes high and a timing interval starts when this input falls below 1/2 of CTRL voltage (which is typically 1/3 Vcc, CTRL being 2/3 Vcc by default if CTRL is left open). In other words, OUT is high as long as the trigger low. Output of the timer totally depends upon the amplitude of the external trigger voltage applied to this pin.

3

OUT

This output is driven to approximately 1.7 V below +Vcc, or to GND.

4

RESET

A timing interval may be reset by driving this input to GND, but the timing does not begin again until RESET rises above approximately 0.7 volts. Overrides TRIG which overrides threshold.

5

CTRL

Provides “control” access to the internal voltage divider (by default, 2/3 Vcc).

6

THR

The timing (OUT high) interval ends when the voltage at threshold is greater than that at CTRL (2/3 Vcc if CTRL is open).

7

DIS

Open collector output which may discharge a capacitor between intervals. In phase with output.

8

Vcc

Positive supply voltage, which is usually between 3 and 15 V depending on the variation.

CIRCUIT REQUIRED

  • pin 1 of 555 Timer IC to negative rail on the breadboard
  • pin 2 of 555 Timer IC to of 555 Timer IC pin 6 and pin 4 of 555 Timer IC to of 555 Timer IC pin 8
  • pin 8 of 555 Timer IC to positive rail on the breadboard
  • 47 k resistor to pin 2 and 3 of 555 Timer IC
  • negative of capacitor 1 connects to negative rail positive to pin 2 of 555 Timer IC
  • positive of capacitor 2 to pin 3 of 555 Timer IC and negative to positive of the speaker and negative of the speaker to ground

WORKING

Once you connect the battery then the circuit will complete and the speaker starts make the sound.
