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.

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

It’s a simple matter of hooking up the Grid-EYE sensor to the Arduino Uno over I2C, and then spitting out the sensor’s data in a nice visual form on a cheap TFT screen. It’s a great ...

Arduino: The Precise Microcontroller. Arduino, by contrast, is not a full computer but a microcontroller. Devices like the Arduino Uno or Nano excel at reading analog sensors, controlling motors, and ...
