/diy/ - Do It Yourself

How can I power and connect several peltier modules and regulate their temperature on the bottom floor of a chinchilla cage? I looked at a tutorial for making a mini portable fridge using Arduino but it was a bit too much for my brain. I know I need an Arduino Uno, a relay, a DHT11 or LM35 temp sensor, and something called a breadboard. I am completely new to this and don't understand most of the terms. For reference my mains power is 240v at 50Hz with British plug sockets

Could use a sensor and arduino, or a thermostat to cut off power at intervals in orther to control temperature.
A heatsink could be anything that is heat-conductive, like just a metal plate glued to the hot part of all the peltier cell together.
putting the cells under the floors with the cooling side facing upwards and the heatsink facing down seems like the best option here as heat will flow to leave towards the sides of the cage instead of towards the floors
