Inexpensive, precision, autorange capacitance meter with a large range.
This is a simple square-wave generator that basically uses the TimerOne library allow you to generate a PWM signal at pin 9.
I am going to present an easy way to know the values of resistors without reading the color bands on them. You'll never need to guessing!
