This is because of the help of the Arduino Microcontroller itself and the If-Else function of the Arduino programming language and also the Pulse Width Modulation. The microcontroller has two sensors attached and able to get its average to display it in the serial port of the Arduino Program ...
the function outputSample(), which prints the Pulse Sensor signal to the serial port will print all of the Pulse Sensor values in succession. When we check to see if there has been a heartbeat, we have to scroll through the Pulse Sensors with a for loop, like this...

A major advantage of pulse jet engines is that they can lift fuel and oxidiser at high enough pressure to function without the need for a turbopump. In contrast, typical rocket engines rely on complex, expensive turbopumps to push fuel and oxidiser into a chamber at a pressure high enough...
The BB-400 uses an Arduino based on the Atmel ATMEGA32U4-MU 8-bit microcontroller to implement it's Digital IO functionality. The controller uses an external
Apple Watch Heart Rate Sensor|Optical Heart Rate Monitor Accuracy|Ultra-Low Power Consumption:The MH-ET LIVE MAX30102 module operates efficiently with a low power dissipation, ensuring long-term reliability in wearable devices. Compatibility with Arduino and KL25Z:The module's 12C interface is compat...
It turns out, oxygenated blood absorbs moreinfrared lightand passes more red light while deoxygenated blood absorbs red light and passes more infrared light. This is the main function of the MAX30100: it reads the absorption levels for both light sources and stores them in a buffer that can ...
In the program code given above, replace the loop() function with the one below: void loop() { Serial.print(particleSensor.getRed()); Serial.print(", "); Serial.println(particleSensor.getIR()); } Now save the code and upload it to ESP32. Go toTools > Serial Plotterand set its ba...

虽然对arduino各板型不熟,但有一点可以肯定,那就是用了atmel的片子。用ida加载,选择atmega32_l没出什么问题,于是就开始上atmel的官网进行查找芯片,最后确定芯片是 ATMEGA32u4,下面就是找板子了。 在这又花了很多功夫,一度怀疑 arduino 是扰乱视线了,因为找到了 GH60 的资料,感觉是改的它的固件,让程序自动输出字符...
