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 ...

a VERY badly made arduino/esp32 project trying to make a alarmclock with a rotary encoder and a floodlight to wake up in the mornings for school this isn't a project for people to learn from im just ...

encoder_gauges.py — 3つの固定ウインドウ（各エンコーダ1つ）に円形ゲージを描画し、 Arduinoスケッチからのシリアルデータをリアルタイム表示するGUIアプリ。

“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 ...

1- O potenciômetro define a velocidade desejada (setpoint). 2- O encoder envia pulsos conforme o motor gira. 3- O Arduino mede os pulsos e calcula o RPM real. 4- O Arduino compara o setpoint com o ...

“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 ...
