Simple Led Flasher Circuit Diagram. The schematic diagram of a simple led flasher circuit is given below. Step 6 connect the pin 3 with the positive lead of led using 1kω resistor.
Step 5 connect pin 6 of timer ic with pin 2. It should start blinking. When the power is turned on the leds start blinking since led1 is a self flashing led it blinks automatically on its operating voltage.
Use 9v or 12v battery or adaptor for this circuit.
The circuit is using three leds which will start blinking or flashing when we provide 9 volt to the circuit. It should start blinking. Circuit 3 of simple led circuits leds in parallel the final circuit in the simple led circuits tutorial is leds in parallel. Here s the schematic shown below is a simplest led flasher circuit.
