Introduction: Arduino Nano Capacitance Meter

About: I'm engineer and like to design electronic and programming things with Arduino hardware.

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:

    Post your sch files please....
    I want to open with eagle...
    Thx

    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 :)
