Arduino Rotary Encoder: Tutorial, Wiring, and Pinout

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 ...

Arduino ロータリーエンコーダー ESP32 AとBの値を可視化してみる

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 ...

Arduino ロータリーエンコーダー ESP32 ポーリング vs 割り込み

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で読み取りたいと思っている。過去の2つの記事でポーリングで実装して、回転させた内容を読み取ることができた。今回、ポーリングの限界と割り込みの導入について ...

rotary encoder

You know, we hadn’t realized how tired we were of vertical laser harps until we saw [Jonathan Bumstead]’s entry into the 2019 Hackaday Prize. It’s all well and good to imitate the design of the ...

Amal-K-Alharbi/Controlling-the-servo-in-a-robot-arm-using-ESP32

This project demonstrates how to control a robot arm using an ESP32, where the ESP32 acts as a Wi-Fi access point and provides a web interface to control the motion range of each servo motor in the ...
