Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. There are many types of security systems available to secure our place. Some examples are PIR based Security System, RFID based Security System, Digital Lock System, bio-matrix systems, Electronics Code lock. In […]

In this project we control direction and speed of a 24v high current motor using Arduino and two relays. No power switches are needed for this circuit, just two push buttons and in Potentiometer to control the direction and speed of DC Motor. One push button will rotate motor clockwise and other will rotate it counter

Arduino shields are boards that will expand the functionalities of your Arduino. You just need to plug them over the top of the Arduino board. There are countless types of shields to do countless tasks. Here’s a collection of 25 Arduino Shields. RECOMMENDED: Read our Home Automation using ESP8266 Course I’ve also wrote a list

L293D is a chip that enable us to control two motors together with only one Arduino board or other microcontrollers. However, I was having a project that required controlling four DC motors together. Recently i brought a L293D Arduino Shields , it covered all of my pins that i need to use them to connect

I’ve used this simple circuit several times to drive motors (like in my Stair Climbing robot) as well as solenoids. I originally picked it up from this instructable which is focused on controlling a solenoid. I wanted to isolate this circuit in its own Instructable as a motor driver so I could easily reference it

First off: I know… we went overboard with the motor illustration. In previous articles we have discussed how to control motors with simple transistors. And… with PWM you could control the speed. But that is just one motor, and you can only go one direction. Today we are going to talk about the TB6612FNG dual

This was an Arduino wheelchair project we developed for Principles and Practices of Assistive Technology (PPAT) in Fall 2016 at MIT. We made an Arduino-based motorized wheelchair controller mount for our client, Lisa. She lives at the Boston Home, a center for people with progressive neurological diseases, and has Multiple Sclerosis. With her old controller

When we need precision and repeatability, a stepper motor is always the solution. With the way it is designed, a stepper can only move from one step to the next and fix in that position. A typical motor has 200 steps per revolution; if we tell the motor to go 100 steps in one direction,
