A 555 TIMER LED FLASHER CIRCUIT


Posted on Feb 6, 2014

An astable multivibrator, often called a free running multivibrator, is a rectangular wave generating circuit. The circuit doesnt need any triggering. The timing of the circuit is determined by the resistors and the capacitors used in it. The details of the astable multivibrator are: Pin1 is grounded; Pins 4 and 8 are shorted, Pin 3 gives the timi

ng output; Pins2 and 6 are short circuited and connected with a capacitor C1; at Pin 5 a bypass capacitor is used having value of 0. 01uF; a supply of 3v is given to the circuit, the suppy can be more upto 9v. Pin 7 is connected through Pin 4 through a resistor R1and also with pin 6 through resistor R2.
