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 ...

前回の私の記事「ESP32とフルカラーLEDで色が変化する和紙製ランプを作ってみよう」と同じ様にLチカネタですが、今回はM5Stack-CでNeoPixelリングを制御して、さまざまなエフェクトをボタンで切り替えられるランプを作ってみます。 また、M5Stackシリーズ用の光 ...

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 ...

“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 ...

Sometimes it’s necessary to make do with whatever parts one has on hand, but the results of squashing a square peg into a round hole are not always as elegant as [Juan Gg]’s programmable DC load with ...

A monorepo containing a React frontend for logging workouts and a Python/FastAPI backend that tracks bar velocity from a rotary encoder at 50Hz.
