Making time for my next small Arduino project, I need to do something with the rotary encoder direction information decoded by this software. A state machine is what I need, but how to implement it?

Uses MQTT to integrate with Home Assistant. Only one pin is technically used but the code outputs to all 3 - this is a lazy way to "correct" a soldering error in my ...

When you’re prototyping a new project, sometimes all you need is a switch. The folks at oomlout were tired of constantly having to rewire things, so they built a universal switch box for the Arduino.

For remote control projects, a text-based serial protocol is often used. In the code for the receiver, switching to the corresponding commands can be done with switch...case in an elegant way. However ...

switch.ino: Arduino の 11 番ピンに接続されたスイッチの状態をシリアルモニタに出力します。 Arduino にこのスケッチを書き込みます。 11 番ピンにスイッチを接続します。 シリアルモニタ（9600bps ...

[Jean-Noel] is fixing a broken Lurem woodworking machine. This machine uses a three-phase Dahlander motor, which has three operation modes: stop, half speed, and full speed. The motor uses a special ...

Here is a simple general-purpose security alarm circuit built on the Arduino platform. It brings up an obtrusive alert signal when an intrusion/theft attempt is observed by its front-end sensor. In ...

Digi-Key Electronics has signed a worldwide distribution agreement with LogiSwitch, makers of the Arduino-friendly NoBounce line of ICs and switches. LogiSwitch’s adaptive NoBounce technology ...

Following Arm’s decision to stop supporting Mbed from July 2026 onwards, Arduino has now decided to use Zephyr RTOS instead of Arm Mbed for Arduino boards that rely on the latter including Arduino ...
