A pulse oximeter takes advantage of the blood’s changing properties when carrying oxygen or carbon dioxide around the body. Oxygenated hemoglobin in the red blood cells absorbs more infrared light while letting red light pass through, giving blood its red color. But when carrying carbon dioxide, hemoglobin becomes dark red, so it absorbs more red…
In the article PProgrammieren des Arduino Nano ESP32 im Arduino Lab I showed you how to flash the Arduino Nano ESP32 for MicroPython using the MicroPython Installer. Here I will show you how to undo the flashing and how to program your microcontroller in the Arduino IDE again. There is an official english documentation under…
