I carnt communicate with the Infrared Laser Distance Sensor (50m/80m) sensor.
Ive wired it up exactly as shown in the tutorial and copyied the code.
I get the error
sketch_may03b.ino:12:34: warning: narrowing conversion of '128' from 'int' to 'char' inside { } [-Wnarrowing]
char buff[4]={0x80,0x06,0x03,0x77};
Please help

If your intention is to convert ascii codes into characters, it is best to use characters directly.
