And You're Done!
Step 5: One Step Furthur ! - Heater/Cooler
1. To Make it Heater / Cooler Connect An DPDT Switch in This Configuration before the peltier module This circuit will just flip the polarity as you change the switch.
2. Connect a bridge rectifier before fan so that no matter what fan will get a proper polarity.
3. With The Flick of a switch it will become cooler or heater, but remember if you're using it as cooler connection of fan on the other side of peltier is essential
