Simple, Cheap Motor Controller

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 from other future instructables and also provide example code to show how to use it in this man ...

Controlling 2 motors with the TB6612FNG + Arduino

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 motor driver, specifically the TB6612FNG breakout board from sparkfun. The TB6612FNG isn’t just a du ...

Arduino Wheelchair Project: Motorized Controller Mount

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 mount, she would often bump into sinks and tables ...

Arduino Stepper Motors

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, it will turn exactly 180 degrees. It gets interesting when we only tell it to go one step and it turns exactly 1.8 degrees ...

The Big Easy Stepper Motor Driver

Stepper (or step) motors are really cool. They are perfect for automation or any time you need a motor to turn to a specific point, at a specific speed, in a specific direction. And, unlike typical motors, steppers are able to do all of this, and hold their position when they are not moving – The trade off is that they cant move as fast, and you have to power them at full power all the time, but you get tot ...

Spining BLDC(Gimbal) motors at super slooooooow speeds with Arduino and L6234

First of all You won’t find here any information on high speed BLDC motor driving. For that purpose You need to know rotor’s position, so You have to measure back-EMF or use Hall sensors (not needed here). For basic info about driving BLDC motors here is best “classic” articles on internets: Driving a three-phase brushless DC motor with Arduino – Part 1. Theory Driving a three-phase brushless DC motor with ...

Arduino PID Motor Controller

INTRODUCTION : The development of high performance motor drives is very important in industrial as well as other purpose applications.  Generally all high performance motor drives use quadrature encoders and PID control because of its simplicity and precise control.  The quadrature encoder acts as a feedback from the motor, it is connected to the microcontroller for furthur processing. With the use of Ardui ...

Servo Motor Simulation via Arduino UNO

Hey everyone. I hope you will be fine. As you know that last time, we had started Arduino UNO course and given you a brief introduction how to simulate the LED blinking via Arduino UNO and its implementation in proteus ISIS. Now, today we are going to implement Servo Motor Simulation via Arduino UNO in proteus ISIS. What is Servo Motor? With the help of servo motors you can position the motor shaft at a spe ...

Brushless DC (BLDC) motor with Arduino – Part 2. Circuit and Software

In this post I will describe the hardware and the software part of a project involving the use of BLDC (Brushless DC) motor salvaged from a broken XBox 360. This is a second installment in the series of posts related to Arduino and brushless DC motors. Please see the first part for a bit of info on the theory behind the commutation sequence. Once you understand the commutation sequence for the particular de ...
