Rohm Semiconductor has developed an evaluation kit for motor driver devices which is designed as a ‘shield’ to plug directly into the Arduino open source board. There different versions of the kit for ...

The Rubik’s Cube was a smash hit when it came out in 1974, and continues to maintain a following to this day. It can be difficult to solve, but many take up the challenge. The Arduino Rubik’s Solver ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

You’d think that we’ve posted every possible clock here at Hackaday. It turns out that we haven’t. But we have seen enough that we’ve started to categorize clock builds in our minds. There are the ...

I like this one - a super impressive Arduino-based barometer for measuring air pressure. There's something satisfying about the link with nature, a tangible connection with outside weather. In a ...

There is hardly any field in the world of electro-mechanics that has not found an application for the stepper motor. They are used extensively in the world of model making and as actuators in remote ...

Stepper motors are available in several versions and sizes with a variety of operating voltages. The advantage of this general-purpose controller is that is can be used with a wide range of operating ...
