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。 本来は、以下のコードで、4つのビットパータンがそろったとき、1回分と判定する必要がある。どの程度、期待通りに ...

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...

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 ...

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 ...

It isn’t hard to imagine a scenario where you are stuck at home all day with nothing to do and certain items are in short supply. Sure, bathroom tissue gets all the press, but try buying some flour or ...
