Arduino Based Temperature-controlled RGB LED

I'm thinking this could be used for knowing when your hot beverage is at a right temperature to be drunk, or warning when it's getting too cold. Could also work for drinks that are better served chilled!

Step 1: What You Need?

1 x Arduino UNO
1 x USB Type-B Cable
1 x RGB LED
1 x Thermistor
1 x Mini Breadboard
1 x 10k Ohm Resistor
1 x 330 Ohm Resistor
Male-to-Male Jumper Wires
Female-to-Male Jumper Wires
1 x Computer with Arduino IDE installed

Optional
1 x Light Dependent Resistor LDR
Cable Cover
Arduino Compatible UNO Ultimate Starter Kit / Learning Kit
USB To Power Jack Cable

Don't have components? Don't worry. Just click the component's name. 

Step 2: Build Your Circuit.

Step 3: Upload The Code.
