Hello,
I know there are some posts about this display but I have not found what I need yet. The root of my program is going to be something really easy, I just need to read an analog input from the arduino and to show the value on the screen. Basically I am going to read a temperature value and I want to see that value on the display. I have tried some code that I have seen online but it does not work.
I am using the ColourLCD library. All the examples on that library work. I can show any message on the screen, any character but when I try to show the value of a variable it shows nothing or get error like impossible to convert from float to char or something like that.
Does somebody know how I could do that?? Thanks!!
