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 ...

“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 ...

モノクロ引き伸ばしLPL 7700の光源をRGBカラーLEDに改造することで、カラー写真の引き伸ばしに挑戦します。 モノクロ引き伸ばし機でカラープリントをする場合、一般にCMYのカラープリントフィルターフィルターを入れてカラーバランスを調整します。

A microcontroller-based waveform generator using the AD9833 DDS chip, featuring a rotary encoder interface and LCD display. Built with PlatformIO for Arduino-compatible boards. The project includes ...

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 ...

As you may have noticed, I’ve been working with an STM32 ARM CPU using Mbed. There was a time when Mbed was pretty simple, but a lot has changed since it has morphed into Mbed OS. Unfortunately, that ...
