Chapter 11. Heating and Cooling

This chapter explores devices for generating heat and also cooling. This includes resistive heater elements and Peltier elements. 

This chapter focuses on how heaters and coolers work. In Chapter 12 we will use the heating and cooling devices described here with Arduino and Raspberry Pi for precise thermostatic control.

Resistive Heaters

Back in Chapter 5, we touched on the fact that in the process of restricting the flow of current, resistors generate heat. As you might recall, the amount of heat generated in watts is the current in amps flowing through the resistor multiplied by the voltage drop in volts across the resistor.

You should now be familiar with simply turning power ...
