Arduino Motor Controller Using an L293D Chip

Controlling DC motors is at the heart of many robotic projects. Servo motors are sexy but DC motors are cheap and a lot more useful to control wheel based robots. In this article I’ll display a “robot shield” circuit that allows you to use cheap motors to drive your robot. Wiring This shield has been built on… Continue reading Arduino Motor Controller Using an L293D Chip

Wireless Arduino/XBee Remote Control with Compass and Accelerometer

A few weeks ago we played with XBee wireless devices. Last week we played with accelerometers and compass. This week we will put it all together in a custom remote control. Our first project will be to remotely control a servo motor by using two Arduinos and two XBee modules. The remote control (transmitter) should be straight… Continue reading Wireless Arduino/XBee Remote Control with Compass and Accelerometer

Netduino Plus (Part 1)

I just received my Netduino Plus. Netduino is an open source microcontroller development board working with the Microsoft .Net Micro Framework. The good news it that the pins layout of the Netduino is compatible with the pinout of the Arduino, which means you can re-use your Arduino shields. The Netduino Plus comes with a microSD… Continue reading Netduino Plus (Part 1)
