relay flasher circuit


Posted on Feb 6, 2014

In this circuit the 555 Timer IC is connected as a astable multivibator and a 12 volt relay is derived through the pin 3 of the IC. The IC generates continues pulses at pin 3 which will activate and deactivate or flash the relay accordingly. The flashing rate per second can be controlled by the 100K variable resistor. The circuit can be operated w
