I have a proyect with a MLX90614(an ir infrared thermometer with I2c), and the output temperature is displayed in a oled 128x64 I2c, I am using an arduino pro mini, the code works well, but i want to add a function:


I want to press a button that saves the temperature shown, in the right down corner of the screen, and if I press it again to save again the temperature.

It is like a memory function, I searched on the internet and I discovered that there is a memory in the arduino called eeproom but i have problems combining that function with the code.

Any help appreciated.

Thank You!!!

I didn't find the right solution from the Internet.
