基于arduino与processing的心率检测计设计研究 基于arduino与processing的心率检测计设计研究 本项目结合Arduino硬件开发平台与Processing可视化工具，设计了一款低成本实时心率监测系统。通过光电传感器采集人体指尖脉搏信号，将模拟量转换为数字信号后实现心率计算，最终在PC端呈现可视化波形与实时心率数值。硬件
When you need a microcontroller to bring your latest invention to life the first impulse is usually to grab an Arduino board, probably an Arduino Uno. It makes sense, the Arduino Uno is easy to work with, and the Arduino IDE is a familiar programming environment with a wealth of libraries ...

For this project, you will need an Arduino Nano (or Uno or Mini or similar so long as it uses a 16MHz ATmega328), a microphone and an amplifier for the microphone. I chose the MAX9814 microphone amplifier as it has automatic gain control. Step 1: Hardware You'll need an Arduino Nano...
