A DC motor controller with control LEDs

Monday, May 15th, 2017

Boris Landoni writes about a new open source project a DC motor controller with control LEDs: It can be controlled through logic levels to set the speed and the direction of the rotation of CC brushed motors and stepper motors; outputs have LEDs indicating the rotation direction. The circuit board we...

App note: Linear speed control of stepper motor

Saturday, March 14th, 2015

An app note (PDF!) from Atmel on Linear speed control of stepper motor: This application note describes how to implement an exact linear speed controller for stepper motors. The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft rotation. Many advantages are achieved using this kind of motors, such...

FPGA : RC Servo and Stepper motor control in Verilog

Wednesday, September 17th, 2014

Trandi blogged about his RC servo and stepper motor project.  He writes: For those interested in reproducing this example: The board is called “EP2C5 Mini Board” and has a EP2C5T144C8 Cyclone II FPGA on it I used a standard, 9grams micro RC Servo I used a 28BYJ-48 stepper motor and it’s...

Easy Stepper motor controller

Monday, March 3rd, 2014

Weiss has written up documentation on his Stepper motor controller: The reason for this project was my frustration over how much it takes to just test a simple stepper motor. To test a stepper motor you usually need some kind of MCU most likely a Arduino, your breadboard, cables, some kind of...

Arduino 28BYJ-48 stepperbot

Monday, December 2nd, 2013

Bajdi's another robotic vehicle with 4 28BYJ-48 stepper motors: The Arduino IDE comes with a stepper library, but I decided to write my own stepper code. For 4 stepper motors I would have needed 16 digital pins and then another 4 pins for the servos. Controlling a stepper motor is...

LMD18245 base Microstep motor driver

Monday, October 14th, 2013

In this video Dilshan Jayakody demonstrates his open hardware project the LMD18245 micro-step stepper motor driver: This article describe the LMD18245 and PIC16F877A base 16 step bipolar stepper motor driver which is design to work with 12V 18º bipolar stepper motors. In this design we use pair of LMD18245 DMOS full bridge motor...

Bipolar stepper motor driver circuit with LMD18245

Friday, September 6th, 2013

Viktor blogged about his bipolar stepper motor driver based on Texas Instuments' LMD18245 build: After extensive research on the internet I decided to make a bipolar stepper motor driver based on Texas Instuments' LMD18245, which is a 3A, 55V DMOS Full-Bridge Motor Driver. It incorporates all the circuit blocks required to drive...

DIY 3D printed stepper motor

Tuesday, April 23rd, 2013

Christopher Hawkins made this cool DIY 3d printed stepper motor: This is a programmable stepper motor and driver that I made out of some nails, magnet wire, neodymium magnets, a digispark microcontroller, and a 3D printed piece that I designed around these things. My goal was to make something about...

Stepper motor bluetooth serial driver (Attiny85 & L293D)

Thursday, April 18th, 2013

Trandi blogged about his Stepper motor bluetooth serial driver project: How to put together a simple bluetooth driver for a nice little stepper motor (Mitsumi M35SP-11HPK) that I salvaged from an old Canon printer. It uses a small Attiny85 (the more I use them the more I love them !...

Yet another stepper driver

Monday, December 10th, 2012

YetAnotherStepperDriver is a breakout board for the DRV8825 stepper motor controller IC. The IC can put out 3A of current, so proper cooling is a must. This is the reason behind so many vias around the bottom pad of the IC. These modules are designed to connect to a booster...

Magnetic loop antenna controlled by Arduino

Friday, October 19th, 2012

This video by Ricardo Caratti demonstrates his method for controlling a Magnetic Loop antenna with an Arduino. The antenna's tuning capacitor is adjusted using a stepper motor interfaced with the Arduino equipped to read IR commands sent from a compatible IR remote control. This allows the tuning capacitor to rotate...

Using stepper motors as generators

Tuesday, January 24th, 2012

Dino played around with some stepper motors by using them to generate electricity. The output is AC so he used a full-bridge rectifier, sometimes refereed to as the Graetz rectifier, to get a single direction signal, basically the absolute value of the sine wave. Check out the video to see...
