I'm trying to send some big numbers ranging from 0-62000 from one arduino to another via serial communication. I'm using unsigned int to hold values from 0 to 65535. And I'm using serial.print() and serial.write () to send numbers and serial.read()-'0' ; to receive numbers, but I'm unable to send and receive numbers above 9. Please help me.
