This library uses a PCF8575 to read the pulses of a rotary encoder. As a PCF8575 has 16 lines up to 5 decoders with a switch can be read over I2C. The PCF interrupt line can be used to detect changes ...

“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 ...

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。

Arduino library for the KY-040 Encoder. This library allows the user to connect one or more encoders to any of the interrupt pins supported by your board. The user may then add rotaries that will each ...

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 ...
