In this article we will discuss and learn about Electronics Circuit – LED Blink using Astable Multivibrator. This is a simple two-LED blink example using the astable multi-vibrator circuit. This circuit generates two different not-stabled state output pulses. We can connect the LED in the two output pulse points and our LED blinks easily. This follows all instructions given to help those who are beginners in electronics. if you know skip what you know already.
