25 Useful Arduino Shields That You Might Need to Get

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 of 21 modules that you can buy for your Arduino for less than $2. 1. Ethernet Shie ...

L293D Motor Controller Tutorial

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 with other breakout board to combine with the motor controller (of course you can buy a L298N motor cont ...

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 ...
