Every Computer Deserves A Rotary Encoder

In the era of touch screens and capacitive buttons, we’d be lying if we said we didn’t have the occasional pang of nostalgia for the good old days when interfacing with devices had a bit more heft to ...

Arduino Rotary Encoder: Tutorial, Wiring, and Pinout

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

Arduino ロータリーエンコーダー ESP32 AとBの値を可視化してみる

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 ...

Arduino ロータリーエンコーダー ESP32 ポーリング vs 割り込み

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で読み取りたいと思っている。過去の2つの記事でポーリングで実装して、回転させた内容を読み取ることができた。今回、ポーリングの限界と割り込みの導入について ...
