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.

This is one of the applications of a 555 timer ic, which is widely used as an LED control circuit. The ic might have a limited use case but the concept of PWM can be used to the wildest of our ...

This 5-color LED flasher circuit can be built using the popular 555 timer and 4017 decade counter ICs. It does not require any expensive components like a microcontroller. The timer IC is used as an ...

All component sizes are beautiful, as evidenced by this amazing circuit sculpture clock. Posted in classic hacks Tagged 1206 , 555 , 555 timer , Circuit Sculpture , flashing Post navigation ...

A flashing LED based on a 555 is not likely to win the first prize for originality, but such a circuit continues to be useful for all kinds of applications. The thing that makes this version special ...

In clearer terms, we’re going to create a pulse-width-modulation (PWM) signal using a 555 timer. This PWM signal can be used to apply a time indicating that something is activated, known as a ...

I can get the LED to blink at various rate using the variable resistance but the AC circuit refuses to work. I use 5vdc as input to the 555 timer (output is 2.9vdc into the optocoupler). since I am in ...

This application of the well- known Type 555 timer is in- tended for model railway en- thusiasts wishing to construct a two-lamp flashing beacon with a minimum of components. With reference to the ...

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 ...
