Testing the Peltier element

I made the first tests of the Peltier with an Arduino board and the Arduino IDE. Then I set off to integrate this practice in the dedicated final project boards.
I used a PID system for temperature control. The sketches therefore inlcude the relevant Arduino library (PID_v1.h).

First assembly of the thermal group

In order to properly work and avoid demage, the Pelier element must be equipped with an heat sink. I therefore assembled what will then be the thermal group in the final project

I adjusted the PID set point to an ADC value of 540 corrsponding to a temperature of 22.4 °C

I also connected an LCD to show temprature and percentage voltage to Peltier (also see the next section).

Testing the LCD

I first soldered the connecting header to the LCD plate. While testing the LCD I also connected the case fan to the board.

The assignment ends with the production of a specific board which, being part of the final project assignment, is detailed in the relevant sections: PCB design and production
