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 […]

How to Control Servo Motor Using Joystick
In this post I have explained how to control servo motors using a joystick and Arduino. We will see overview about joystick, its pins, its construction and working. We will be extracting useful data from the joy stick which will be base for controlling the servo motors. Introduction The motto of this article is not […]
High Current Motor Control Circuit using Arduino
In this project, I have explained how to control motor speed using Arduino PWM circuit, and how to implement reverse forward or direction control in a DC motor using Arduino through a couple of push button switches. Any high current motor upto 30 amp can be controlled using this set up. Introduction Motor is a […]
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. […]
Simple 220V AC Fan Regulator Circuit using Push Button
In this post we learn about this 220V AC electronic fan regulator circuit using a push button which changes speed step by step with each press. We press the button, then circuit cleans the signal, counts it properly, and then selects a relevant fixed speed level. Each button press moves the fan from OFF to […]
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 […]
