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 ...

制御用のArduinoには 秋月電子通商 の Arduino Pro Mini 互換の AE-ATMEGA328-MINI を用いました。 搭載されているCPUはATmega328P (5V)です。 LED3個とスイッチ1個、ロータリーエンコーダのAとBの端子2個をArduinoの適当なデジタル入出力端子に接続します。

“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 ...

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 ...

So, I'm halfway through designing my future rackmount cabinet, and I hit upon the idea of embedding a LCD display in the front door, with some method of controlling the LCD, plus maybe the main volume ...

There’s something to be said for the feel of controls. Whether it’s the satisfying snap of a high-quality switch or the buttery touch of the pots on an expensive amplifier, the tactile experience of ...

I want to write about something a little different this time. I removed the mechanical scroll wheel rotary encoder from a discarded optical mouse and used it in a little project. I really liked the ...
