    555 distorted square wave output

    Hi, I built a standard 555 timer circuit for a square wave output signal of 10 Hz. It is the standard circuit for the astable mode, as given in Wikipedia: C = 1 uF, R1 = 6.8 kOhm, R2 = 68kOhm, in my case a 100 kOhm potentiometer. The circuit was mounted on a breadboard and drives a LED with a...

    Problem with high and low of 555 astable timer

    Hello. I just wanted to give a brief introduction of the type and purpose of my circuit. The circuit is designed to turn on (go high) for a time determined by 0.693R1C1 and do this (go low) periodically after a time determined by 0.693R2C2. I got this operational by using two diodes D1 and D2 on...
