PWM controller for DC Motor using 555 timer IC

pwm motor speed control

Pulse Width Modulation PWM controller. PWM is a technique in which the amount of current going in a circuit can be controlled by chopping the Direct current using a gate or transistor that is changing its duty cycle( on-off time) you should see this article flashing of LED using 555 IC. This article is about how you can control the speed of a DC motor using PWM motor controller Must watch this video for better understanding.. This PWM circuit can be easily found in our daily life equipment like mobile…

Working of 555 timer IC explained

555 timer ic pinout

How does the 555 Timer work? NE555 is one of the most popular and widely used ICs of all time. In this blog, we will discuss the working of 555 timer IC. Overview The 555 Timer was designed by Hans Camenzind in 1971. It can be found wast variety of electronic devices. It is used to produce time delay and a square wave of a wide range of frequencies. It is highly accurate and stable. The 555 Timer has three astable, monostable and bistable mode. To understand the working of…

Flashing LED with 555 timer

In this blog you will see how to make Flashing LED with 555 timer. 555 IC can work in three modes Astable, Monostable and Bistable, out of which we will be using Astable mode of working. Watch this video to understand better Overview: In astable mode 555 timer continuously oscillates between 0 and 1 ( on to off). By using a Potentiometer and a suitable capacitor you can control the frequency and duty cycle of of output wave at pin number 3 of 555.   Components required: 1.) 555 timer…
