However, it can be argued that since the exponential voltage of a capacitor is qualitatively similar to inductor current, the latter can be made an alternative timing element for the 555. This was ...

The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the most widely used ICs due to its reliability and flexibility.

A 555-timer IC can inexpensively perform PWM. The circuit in Figure 1 shows how to turn a 555 PWM circuit into an switch-mode power supply with only one simple equation. The design uses two 555s. IC 1 ...

Just about anything can be made with a 555 Timer, and every circuit is fun to build, which I show in my book “Essential 555 IC: Design, Configure, and Create Clever Circuits.” In the book ...

The circuit is quite basic. The 555 timer outputs in astable mode, which means there is a continuous stream of pulses from pin 3 which go right into the speaker circuit. The rest of the circuit ...
