LED chaser lights (or) sequential LED flasher circuit on a breadboard using 555 timer + 4017 IC and a few other components. The LED’s chasing rate can be adjusted using a potentiometer in place of 47K ...

parts list, circuit diagram & testing or you can continue reading the post for further details. A simple LED chaser hobby circuit can be made using 555 timer and CD4017 counter IC. You can use this ...

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 ...

This is a small size led flasher built with the 555 timer IC that is powered from 2 x 1.5V batteries. The circuit can be used as a flashing metronome, dark room timer, memo-reminder or other similar ...

This simple LED driver circuit allows us to drive up to seven LEDs by using a single NiMH (Nickel Metal Hydride) AA cell. The circuit produces voltage pulses at a much higher level than the input ...

LEDs are commonly used in electronic circuits as they consume less power, are easy to use, and have a long lifespan. In this tutorial, we will learn how to build an LED ON and OFF circuit using 555 ...

The 555 timer IC is a well-known integrated circuit having been widely used as a pulse generator. We propose a circuit containing a single 555 IC, an LED, an inductor, two capacitors, and three ...
