Turns on and off a light emitting diode (LED) connected to a digital pin, without using the delay() function. This means that other code can run at the same time without being interrupted by the LED code. The circuit: - Use the onboard LED. - Note: Most Arduinos have an on-board ...

我们今天用到的MAX30102模块既可以用来测量心率，，也可以用来测量脉搏血氧浓度；采用标准I2C通信接口，可通过软件关断模块，实现超长时间待机。据说三星Galaxy S系列手机就大量应用了此模块。OLED的全称是OrganicLight-Emitting Diode，即有机发光半导体，通过有机分子发光。相较于LCD或LED，OLED的优点还挺多的：更加纤薄...
