I'm having trouble with uploading the code, it will randomly say that something went wrong and it won't tell me why. I'm a beginner at this stuff so I need help, please.

Hi, fantastic project, congrats! Super-newbie question (first contact ever with Arduino!): you use "Arduino Nano R3" but it looks like it's currently retired, not possible to buy. What should I buy instead, and would these instructions still apply? Thanks a lot!

everything is great but how do you stick the LEDs into the cardboard, i thought you put them on a breadboard and it's not going to fit the project

I like your idea and was going to help my 3rd grade daughter to build this for a project for school. I am new to this world but old to computers. Can I use a arduino uno for this project? If so what would be the difference in wiring, if any. How would I wire a 16 x 2 lcd up to display results also?

Get the latest version of the Arduino software, which I think is 1.6.8. Then, load the program onto your uno, mini, etc., and keep your USB connected to your computer. With the Arduino IDE displayed on your computer, click "tools" in the menu. You will see "Serial Plotter" as one of the selections. Select this and you will see the plotter come up with a straight horizontal line until you place your fingers on the sensor pads. Good luck!

Hello, I did the editing on my arduino Uno, everything seems to work. I have 1023 that appears on the plotter serie when I connect my 2 son and leds are ok too. But when I put my fingers on the son (with or without aluminum) I have no current that passes. The serial monitor remains at 0 .... someone has been faced with this problem? thank you

Great project! I changed it a little: added 330k resistors to the LEDs so they don't burn up, changed the A0 resistor from 2K to 100K to produce a wider range of response, used common tacks for finger pads, and added another LED for more range. Thanks for the effort!

Be careful when doing this project. After having fun and testing the whole set up for several minutes in a row, I just started to feel a small pain in one of the fingers so after removing the finger clips, surprise surprise: tinfoil had burned a bit my skin. Just be aware of risks.
