The table shows the pin configuration of the Arduino UNO–based robotic arm. The red (VCC) wires of all servos are connected ...

The EEWeb Design Contest First Edition sponsored by Arduino and Altium is now open for submissions. This inaugural contest challenges hardware design enthusiasts from all over the world to develop an ...

A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...

Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow for much ...

This is the first part exploring the motor control shield that I designed for the project where I was doing 3D Printer Filament Measuring with Arduino. The DC motor portion of the project is based on ...
