NeoPixel Thermometer!

My project is very simple and easy to accomplish. I chose this project to monitor the temperature of my room because having a guinea pig I should know the temperature because too low or too high could die U_U. My NeoPixel has 12 LEDs, the base temperature is 11 ° C and the maximum is 30 ° C, each LED has a temperature range of 1.5 (ie the first LED will light if it is at a temperature Between 11 and 12.5 degrees). To understand the temperature I printed on a sheet of temperature and then after bending I put it in the NeoPixel.”
