Hi!
I have tried all the means. I have removed the old Arduino 1.0 files, libraries and then installed the Arduino 1.0.1 files. But the same result is persisting. I am puzzled. I hope the mistake is in the LIQUIDCRYSTAL.H file. It is expected to provide no output (void), but the programme is asking some return at the end. How to cope with the LIBRARY FILE? I have done all the motor programming, LED display, sensor data reading etc. But I have stucked here. Please help me.
