Nope not planning to use the second 328 for anything other then to just listen to the first 328 and print out what it says...it only for debugging purposes ..since I use atmel studio not the arduino ide getting a serial output window is harder so I just made this for that purpose.
Plastic dip is made by the same people who make liquid electrical tape...they just call the two products by a different name but for the most part its identical. A rubber non conductive and removable coating.
Yeah it was 6 dollars at homedepot
