This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute ...

このプロジェクトは、Arduinoを使用して筋電位（EMG）信号を取得し、FFT（高速フーリエ変換）を行って周波数成分を分析するものです。EMG信号の周波数分析により、筋肉の活動状態や疲労度などを評価することができます。 このプロジェクトはMITライセンス ...

This project is a Fixed Fast Fourier Transform (FFT) Spectrum Analyzer built using an Arduino Nano, a 0.96" OLED display, and a MAX9814 microphone module. The analyzer visualizes audio frequencies ...

If you’ve ever wanted to make your own VU meter but were scared off by the signal process you need to study this tutorial. The one drawback to the hardware choices made here is that there are only ...
