Thermoelectric Cooler
This project aimed to create a constant temperature copper plate, with a temperature ranging from -5 to 15 Celsius degrees; that was achieved by utilizing a PWM (Arduino Uno) to create a closed loop feedback system. The peltier cooler is placed between two copper plates in order to create a temperature difference and create a hot surface. Also, a heat sink is placed on top of the system for temperature control, and to avoid overheating.
