Im new in this forum. I have a problem with some variables that i want to print in the serial lcd 128x64. In my code, i use some variables int andf float to make some operations, but when i want to show them in the lcd appear more characters that dont have to appear! (Using Serial.print and Serial.printl) and i dont know why they are showed.
I hope somebody can help me with it, i have tryed to change all the variables to int type and all float, but is the same problem.
I left the link where my code is.https://dl.dropbox.com/u/57429772/Pantalla/Pantalla.pde
PD. The errors just appear when i print the variable level, porcentage and litros.
