This project showcases a control system built with an Arduino microcontroller, featuring an LCD display and rotary encoder. Users can navigate through various modes, adjust real-time measurements with ...

/* 3個のスイッチ付きロータリーエンコーダ（A, B, C=GND, SW）を読み取り、 回転イベント（クリック単位）とスイッチ押下 ...

This project is an electronic voting system that uses a fingerprint sensor, an RFID reader, and a rotary encoder for navigation. The project also monitors the battery level and displays the battery ...

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 ...

“Measure twice, cut once” is great advice in every aspect of fabrication, but perhaps nowhere is it more important than when building a CNC machine. When precision is the name of the game, you need ...

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 ...

An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive ...
