Automatic Dispenser Using 555 Timer

The 555 timer has been a popular choice in electronics for a long time due to its versatility and wide range of applications.

It can be used as a timer, oscillator, frequency divider, frequency modulator, triangular signal generator, and more.

The 555 timer has three main modes: monostable, astable, and bistable.

In this article, we will explore a new mode of operation for the 555 timer that generates a unique pulse when the circuit is powered on.

Unique Mode of Operation for the 555 Timer

The only way to generate another pulse is by turning off the circuit and then powering it on again. While one might think that this can be achieved with the monostable mode by setting pin 2 to low (ground), doing so would result in the output of the 555 timer always being on.

(You can try this yourself)

In this particular monostable mode, pins 5 and 7 are not used. Fig. 1 illustrates the circuit diagram of this specific monostable circuit.
