秋月電子通商で購入できる「LED付ロータリーエンコーダー(赤)ツマミ付セット」をESP32で、1msec間隔でポーリングして、AとBの値を監視して、グラフにしてみる実験。 理想では、「右回り (CW): 00 → 10 → 11 → 01 → 00」、「左回り (CCW): 00 → 01 → 11 → 10 → 00 ...

“I looked at all the available rotary encoder sketches and none of them met my needs, so I have written my own, and here it is”. Well, I looked at all the ...

以前、秋月電子通商で「LED付ロータリーエンコーダー(赤)ツマミ付セット」を購入した。これをESP32 Arduinoで使う方法を入門してみる。

One of the redeeming qualities of many modern cheap keyboards is the built-in volume control buttons. But this is Hackaday, and many of us (and you) have Model Ms or newfangled mechanical keyboards ...

Volume Dial is a wireless hardware system designed to control a computer’s audio volume using a magnetic rotary encoder. The system is built around multiple ESP32-WROOM-32 modules that communicate ...
