The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

Watch the video below to learn more about this awesome DIY Arduino watch that uses a GY-87 sensor board, that offers three sensors in the form of HMC5883L for the compass, BMP085 for the pressure ...

T. K. Hareendran shows us a simple setup to explore the capabilities of the Bosch BMP280 pressure sensor with your Arduino.

The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...
