Digital Capacitance Meter Objective The aim of this project ... Components Required Arduino Uno 1k ohm resistor 10k ohm resistor Polarized capacitor LCD display (16x2 or similar) Breadboard and jumper ...

I ended up using a buck converter to power the servo so the path with the capacitor was no longer needed ... a new battery holder for the 4 AAA's that power it. I decided on an Arduino nano as the ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.
