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 ...

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 ...

このプログラムでは、Arduinoと液晶ディスプレイを使って「水晶玉占い」のような機能を実現しています。傾斜スイッチが反応するたびにランダムな答えが表示される仕組みです。 #include <LiquidCrystal.h> LiquidCrystal lcd(12, 11, 5, 4, 3, 2); const int switchPin = 6; int ...

“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 ...

This project is an Arduino-based clock and counter that uses GPS time signals to maintain near-atomic-clock accuracy. It features a ten-digit seven-segment display for showing the count or time, and a ...

“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 ...

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 ...
