This is a really simple ambient display for temperature using an arduino, an adafruit RGB backlight LCD, and a temperature sensor. The LCD displays the temperature in Fahrenheit and Celsius and adjusts the color of the backlight depending on the reading. An ideal range is set at 61F to 67F. If the temperature is in this range the backlight will change green. Above this range and the color will change red, below the range it will change blue. The great thing about these kinds of displays is that you can immediately get some rough information from across the room.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

I actually made one if these when the adafruit RGB LCD first came out. My addition is the ability to adjust the upper and lower limits via pushbuttons. My first project actually. I need to get back to it and add the 2.0 functionality I came up with. Grea product Adafruit.
