Goal: Use a joystick to control a stepper motor's speed and direction. The joystick input determines motor rotation speed and direction.

⇒ UART Configuration : One of the most powerful aspects of the TMC2209 is its single-wire UART interface. With UART, you can configure motor current, microstepping resolution, operating modes, and ...

Stepper motors use a cogged wheel and electromagnets to rotate the wheel one ‘step’ at a time. Each HIGH pulse sent to the A4988 stepper driver energises the coil, attracting the teeth closest to the ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

It’s fair to say that building electronic gadgets is easier now than it ever has been in the past. With low-cost modular components, there’s often just a couple dozen lines of code and a few jumper ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer. The following is excerpted from the ...

Arduino’s brand-new Esplora microcontroller, packed with prebuilt sensors and features, could indicate a move for the DIY electronics company toward a wider segment of the microcontroller market.

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 ...
