This is a simulation of classic Astable Multivibrator circuit built using two NPN transistors, resistors, capacitors, and LEDs. It continuously switches between two unstable states, causing the LEDs to blink alternately. The capacitors and resistors control the timing, creating a square wave output without any external clock input. It's a simple and effective way to demonstrate basic oscillator behavior in electronics. #ElectronicsEducation #electronicsrd #multivibrator | Electronics Education
