The ESP32 keeps finding new jobs in my house.

On a chessboard, a pawn moves forward on its own. A knight jumps in an L-shape. A rook slides in a straight line. All 32 pieces are independent robots. Moreover, it is open-source and anyone can build ...

There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

The Raspberry Pi Pico is a microcontroller development board powered by the custom RP2040 chip. With its dual-core ARM Cortex-M0+ processor, extensive GPIO pins, and built-in programmable I/O (PIO), ...

Plug it in with a Stemma QT cable for instant rotary goodness, with any kind of microcontroller from an Arduino UNO up to a Raspberry Pi. You can use our Arduino library to control and read data with ...

A rotary encoder provides Microsoft Surface Dial-compatible controls on Windows, while 2.4GHz Wi-Fi enables clock synchronization and OTA firmware updates. It also supports USB PD power input and ...

To measure the motion of wheels by odometry, two rotary encoders of 20P P R 20 P P R (pulse-per-revolution) are coupled to each reducer shaft of the motors. To operate the motors, a dual motor driver ...
