Arduino Capacitor Meter Theory
Video Based on This Circuit: lesson-14-arduino-capacitor-meter
Code for This Circuit: lesson-14-arduino-capacitor-meter-code
Small Correction to Video!
The connection should be like this:
Digital CTRL Pin -> Resistor -> Capacitor -> GND
Between the Resistor and Capacitor we connect the Digital-Input
(In the Video I have by mistake replaced the place of Capacitor and Resistor, all other is OK)
