Astable Multivibrator Design using 555 Timer IC

f_astable_multi

Astable Multivibrator is one of the many uses of 555 IC. Astable means the output is not stable in any position whether it is high or low. It continuously fluctuates between high & low state so we can call it an Oscillator. Here we demonstrate how to design a rectangular wave oscillator using the most popular 555 timer IC and calculate other components value for a required frequency. Lets see the pin allocation of 555 … Continue reading
