About: I'm engineer, I like to design programming things with Arduino hardware and pure electronics too.

This project is practically three components because it's formed of a 16X2 LCD Display, a potentiometer 10K, and an Arduino Nano while the rest of parts are a PCB designed by me using EasyEda software, 1 X 40 HEADER, 0.1" SPACING, and 1x6 FEMALE HEADER. This tester can measure from 0.000 to 1mF.

Step 1: Bill of Materials

What you will need:

1-Arduino Nano

1-16 X 2 LCD Display

1-PCB designed by me using EasyEda software

1-10 K Potentiometer

1-1 X 40 HEADER, 0.1" SPACING

1-1 X 6 FEMALE HEADER

Soldering Iron

Soldering 60/40 roll

Step 2: Schematic

This is your schematic so that you can construct the project correctly. The diagram contains detailed information to complete it without any problem.

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 1 x 4-pin and insert it from under the Arduino nano and solder on (5V, RST, GND, Vin). Now, cut 1 x 15-pin and insert it from under the Arduino nano and solder on (D12, D11, D10, D9, D8, D7, D6, D5, D4, D3, D2, GND, RST, RXD, TXD). Finally, insert the 1 x 6 FEMALE HEADER diractly on the Arduino nano between A0 and A5 and solder it under the Arduino.

Step 5: Installing the 10 K Potentiometer

Insert the 10 K potentiometer directly on your PCB and solder it.

Step 6: Installing the 16 X 2 LCD Display

Insert the LCD directly on your PCB and solder it.

Step 7: Installing the Arduino Nano

Carefully insert the Arduino nano directly on the PCB and solder it.

Step 8: Complete Your Project

Once completed your project, you can upload the code. For that, you should visit the next website: https://pastebin.com

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 :)
