The 555 can be used as an amplifier. It operates very similar to pulse-width modulation. The component values cause the 555 to oscillate at approx 66k...
You all must have seen the circuits for amps. They are very easy but sometimes if you are a noob or you can't find the things required for it you can't make it. In this instructable you will learn how to make an amplifier from 555 ic.
Step 1: About the 555
To make this amplifier you will need to know about the 555 ic's pinout. The pinout is given in this step.
