555 Timer IC provides time delay in circuits and here we discussed its pin diagram, various modes, working, circuits, and applications.

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 ...

555ic_motordriver Motor speed controller using 555 timer ic in astable multivibrator mode to produce the PWM pulses necessary for control over the speed of the motor. A 555 timer ic, operating in ...

Fortunately, both the speed and direction of a DC motor can be controlled via an Arduino microcontroller. Let’s get into details. Direction control A circuit known as an H-bridge may be used to alter ...

This paper proposes an investigative study on DC motor braking system. Electro-magnetic relay and timer are deployed for this purpose in DC shunt motor. Plugging and dynamic braking systems are ...

In this project we build a simple boost converter circuit using a 555 timer IC. Boost converter is a non-isolated type of switch mode power supply that is used to step-up the voltage.

Let’s Look at the Schematic In a PWM circuit, the 555 timer will output a logic signal “high” and “low” depending on a ratio derived by the value of a few components connected.
