The problem Hi, I have a wemos D1 mini pro with an uln2003 to drive a stepper motor (28BYj-48). It works well but the motor is only spinning clockwise (and doesn't spin couterclockwise) no matter if I ...

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.

However, if the primary space limitation is motor diameter, engineers can increase step-motor torque within a given frame size by increasing the motor’s length.

Capturing images one at a time A rotating base operated by a stepper motor is controlled by Arduino Uno and ULN2003 driver board. Upon this base, an object is placed that has to undergo 3D scanning.

An Arduino-based 3D scanner was created by an industrious 3D printing enthusiast and released open source this week for all to enjoy. This open source… ...

The design of this stepper motor is simply two coils of wire, with the X axis of the grid placed on the top copper layer of the PCB and the Y axis on the bottom copper layer.
