The function of the 555 timer is mainly determined by two comparators. The output voltage of the them controls the state of the RS flip-flop and the discharge tube. It also contains 3 working states.

This is an interesting project circuit named TV remote jammer circuit that helps to confuse the IR receiver present in TV by producing constant signal which interferes the remote control signal. This ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...

It’s back! The 555 timer contest wants to see you do something cool with the 555 timer chip. At stake is the adulation of electronics geeks everywhere. Three top winners will be awarded a $150 ...
