Introduction: Arduino Nano Capacitance Meter

This project is pratically three components because it's formed of a 16X2 LCD Display, a potentiometer 10K, and an Arduino Nano. The rest of parts are a PCB 5cm x 7cm, 1 X 40 HEADER, 0.1" SPACING, and 4-625" STAINLESS STEEL HEX STANDOFF, M-F, 6-32. In a nutshell, Capacitor Meter can measure from 0.000 to 1000uF.

Step 1: Bill of Materials

What you will need:

1-Arduino Nano

1-16X2 LCD Display

1-5cm x 7cm PCB

1-10K Potentiometer

1-1 X 40 HEADER, 0.1" SPACING

4-625" STAINLESS STEEL HEX STANDOFF, M-F, 6-32

Some Connecting wires

Soldering Iron

Soldering 60/40 roll

Step 2: Schematic

This is your schematic so that you can construct the project correctly.

Step 3: Preparing Your LCD

Taking the 1 X 40 HEADER, 0.1" SPACING, cut 16 pins and insert that part in your LCD.

Step 4: Preparing the Arduino Nano

Taking the 1 X 40 HEADER, 0.1" SPACING, cut 6 pins and 3 pins and insert those parts in your Arduino Nano. That is, the 6 pins are to install in D2-D7 and +5V-GND pins.

Step 5: Installing the LCD

Why don't you design your own character for "µ" instead of using the silly "u"? If my memory serves me right, you can design up to 8 custom characters with these LCD displays. Imagine how much more professional would your project look.

I wonder why AVR transistor testers can only measure down to 36 pF? You seem to have no problem going to 0 pF.

oh and try Cadsoft Eagle (free) for making schematics and high quality PCB files, so much easier and very powerful software :)

KiCAD is really free.
