This project was inspired by the legendary electronics hobbyist author Forrest M Mims. There is an example circuit of XOR hardware encryption using a few CMOS logic chips (4000 series) in the digital electronics book in his famous Radioshack Electronics learning lab kit. As most hardware hackers, I was on standby waiting for my team to finish the software side of things, and worked on a personal project, that I did not intended to spend time to actually submit as a project. As I was flipping through the PDF version of the digital electronics book, this project caught my eye, and I didn't have most of the CMOS parts to do the project, but replaced them with TTL equivalents. Then, I came to the realization that for the signals, I did not need to use the circuit in the book! I could use my Electronics Explorer board and an Arduino. I also realized that for the transmission part of the circuit (Data transmitting to the other gate)...
What is this thing doing? Would you mind adding some description?
Btw, how do you get >2K followers while this project has only 618 views?
