Figure 1 The block diagram of the 555 timer IC is simple, but its applications are varied and numerous. Source: Texas Instruments For hobbyists, the 555 has been a valuable entry point and platform ...

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 ...

The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows ...

Before going into detail of Time Delay Circuit, first we need to learn about 555 Timer IC first. Below you can find the pin diagram of 555 timer IC along with the details of each pin.
