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 ...

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 ...

Circuit Diagram The 555 timer is the most commonly used IC for many different applications, which is what the working of the circuit is very simple when the voltage at pin-2 falls below ⅓ of the VCC ...
