App note: CPLDs as Motor Controllers

Saturday, January 4th, 2014

Here's a simple motor controller implementation using CPLDs from Xilinx. To enable a CPLD to turn the electromagnets on and off, external transistor drivers must be used. A unipolar stepper motor can be driven by four identical NPN or N-channel drive transistors. The various Xilinx CPLDs can operate with I/O...

IR proximity motor control

Friday, January 4th, 2013

Chris from PyroElectro writes informing us of his project to achieve Motor Control via Proximity Sensing. He describes, "In this article, we go step-by-step through the process of understanding, designing and building a system that uses an infrared proximity sensor for input, correlates that input to how far away an...

Robotic motor control tutorial

Saturday, May 12th, 2012

Chris from PyroElectro has written a multi-part tutorial on building motor control firmware for a microcontroller, a PIC 18F252. This tutorial is based on his earlier robot chassis, but the principles relating to the use of a motor controller IC (SN754410) to move the motors at specific speeds and directions...

GOduino II motor driver

Tuesday, April 10th, 2012

Hazim Bitar writes in about the GOduino II motor driver project. In addition to the Atmega328p w/Opti bootloader, he uses a L293D h-bridge and various supporting caps and resistors giving the project a total estimated cost of about $20. Visit the TechBitar blog for project build details, along with schematic...

Altera’s BeInMotion FPGA motor control kit

Saturday, July 16th, 2011

In this video from Altera, they highlight the advantages of using FPGAs in motor control. The video is based on BeMicro's BeInMotion SDK motor control kit from Arrow Electronics. Looks interesting, however the $79 hardware kit isn't yet in stock, and the BeMicro SDK is sold separately for $79. A...

Reversible motor control for Arduino and other MCUs

Thursday, April 14th, 2011

Nothinglabs has posted their circuit for a simple reversible motor control for use with the Arduino and other MCUs. The circuit uses two TIP120 Darlington Transistors, two 220 ohm resistors and a 12 volt DPDT relay, parts easily obtainable at any Radio Shack. This design supports PWM for variable speed...
