This is a fork of Mirko Pavleski's simple capacitance sensor. The key difference is here we are using a standard 16x2 LCD screen, with an I2C interface for the screen. The orininal ST7565 screen though nice is not something I have on hand.

Differences from Original Code:

Simplified Measurement Handling:
The Cyfry function in the original code handled the conversion and formatting of the capacitance value. The new code does this directly within the loop function.

Direct Display:
The new code displays the measurement directly on the LCD without intermediate processing, reducing complexity.

Range Handling:
The new code uses simpler range checks (if statements) to determine the units (pF, nF, uF) and display them accordingly.

Improved Readability:
The new code is more readable and easier to follow as it combines measurement, processing, and display in a straightforward manner.
