The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.

For example, if we have a high (1) output, it will go low (0) once it receives an interrupt and stays low (0) till the next interrupt changes the status. More technical details can be found in the 555 ...

This paper reports an industry standard monolithic 555-timer circuit designed and fabricated in the in-house silicon carbide (SiC) low-voltage bipolar technology. This paper demonstrates the 555-timer ...

A scan of the Archer Engineer's Mini-Notebook 555 Timer IC Circuits sold at Radio Shack. This book by Forrest M. Mims III has multiple designs for various circuits using the 555 timer IC. Each page ...

In this traffic light project we are going to design a circuit, to control traffic lights on a four-way signal. This circuit is designed by 555 Timer IC and a decade counter. The timer generates ...

An example is a high-temperature environment which can shorten the useful life of electrolytic capacitors. In that case, the circuit in Figure 1 is worth considering. Figure 1 A 555 multivibrator ...

For example, a 50% duty cycle will have the circuit load “on” for half the time. In this project, we’ll apply a variable PWM signal to control the intensity of an ancient evil object.

RGB bulb using 555 timer circuit Circuit diagram of the RGB bulb using 555 timer is shown in Fig. 2. It is built around 230V AC primary to 12V-0-12V, 500mA secondary transformer (X1), a 5V regulator ...
