hi. i'm new to arduino.
while i'm compiling the program above, i keep getting this message: In function 'void sendStringToFlash(char*)':
error: 'printByte' was not declared in this scopeCouldn't determine program size: hardware/tools/avr/bin/avr-size: '/tmp/build61187.tmp/ledTester.hex': No such file
