Hello and good day sir.
I'm doing my research project on PID controller using ARDUINO to control temperature of Thermoelectric cooling material. While searching for my reference, i'm stumbled upon your video
While your project was focusing on the heating, my project is want to get the cooling temperature. I just want to know your opinion whether i can implement your project and change some of the specification like power drive or something else so that it can suits my project? what do u think sir?
