Hello, I am new to Arduino and coding. We have got a class project where we are going to make our own "robot" that collects data over certain things.

I tought of having a sensor that has the data over the room temperature all the time, and when the classroom (which we are going to use it in) gets too hot or too cold, there should be a light signal which signals that the room temperature needs to be changed. (Specially in colder seasons in Norway, classrooms get overheated and often too cold, a classroom should be about 18-25 degrees).

My plan is to have some sort of lights forexample: green light -> the room temperature is okay
red light -> the temperature is too hot
blue light -> the temperature is too cold.

Do anyone know what parts I need for this;)? Thanks:D.

What do you have so far? A minimal version would use a DS18B20, three LEDs plus a resistor for each and an arduino. I expect you'll breadboard it to start with, so you'll need one of those and some interconnect wire.

It sounds like you just need any Arduino, 3 LEDs (or one RGB LED that changes colour) and a temperature sensor (there are loads of these of varying price and quality, just search "Arduino temperature sensor").

A little more searching for something like "Arduino room temperature" will find you many very similar projects that people have already made.
