“I recently developed a prototype of my own Arduino based phone. Time to improve it.
In the previous video, I built a phone on a breadboard that I called CoolPhone. I had no major problems with the prototype, I just had to eliminate noises on the microphone and speaker. So it might seem that the rest of the project will go smoothly, and it should be, but it turned out a bit differently. After all, CoolPhone works, but let me tell you now that I have plans to make it better. But from the beginning.”
