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 ...

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 ...

/* 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 ...

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 ...

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 ...

“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 ...

“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 ...
