Making the heater
Final documentations
This is the code I ended up using after iterations to control the polarity of Peltiers and using four of them with four drivers. I implemented the PID control system from the pre-existing api.
Basic rules were that:
1) Temperature is regulated to keep the sugar glass melted to around 55 celcius degrees (In hot mode).
2) Once button is pressed, it drops the temperature by reversing polarity
3) Once it reaches the cooled temperature (minTemp 20), it goest through 9s stableTime to declare it's been cooled.
4) Then it switches back to hot mode.
Very Basic Interaction Looks As such:
** On the hindsight, I regret designing and making the whole framework first, before working with multiple drivers (Peltiers). It could have been an equally interesting system with just one heater devised. Note that the final "look" is very empty due to my inability to fill or use the right power supply to operate 5 h-bridge drivers.
