Hi, i'm doing a project for my university study, and its about temperature monitoring. The background of my project is that i want to display the condition of the temperature. Example= if temperature is 10-30 C, the LCD wil display 'COLD WATER'. I think i've done what i can, yet when i run it in the proteus, no display on the LCD. Can anyone help me? i need help ASAP guys, thanx
below is the code
