In this post I have explained what servo motor is, how it functions, how to interface with microcontroller and what make this motor special from other motors. Being an electronics enthusiast we would have come across many kinds of motors, here we are going to take a look at special type of motor called servo […]

Automatic Curtain Open-Close Circuit
We are happy to share an automatic curtain control circuit kindly provided by Mr. August Peterson. This design helps to open and close curtains by sensing light from the surroundings. It uses an LM393 comparator, a solar panel as a light sensor and a 24V motor. The circuit makes the curtain open in the morning […]
Servo Motor Working Explained
We know that servo motors already exist for very long time and we also see that many people use them in many applications. These motors look small but they give big power and also they save lot of energy. So now many people who like electronic things and who want to understand more about such […]
L298N DC Motor Driver Module Explained
In this post I have explained about L298N dual H-bridge DC motor driver module which can be used to drive brushed DC motors and stepper motors with microcontrollers and ICs. Overview Modular circuit boards are best time savior for electronics designers which also reduce the prototyping errors. This is mostly preferred by programmers who write […]
A4988 Motor Driver Circuit Diagram with IC 555
In this article we now talk about a very simple but very useful stepper motor controller that uses one A4988 driver module and one 555 astable pulse generator. Overview Of The Circuit So we first see the main building blocks. We have one A4988 module that drives any small 2 phase stepper motor. We also […]
3 Phase Solid State Contactor Circuit: Electronic ON/OFF for Motor Pumps
In this article I have explained how to design and build a solid state contactor circuit using triacs, with ON OFF push electronic switches, for operating heavy duty loads like submersible borewell pump motors with high reliability, and without any concerns about wear and tear issue or long term degradation issues of the contactor unit.
