( N00b alert.. )
Hi everybody, i have a problem which is probably a piece of cake to solve, but i can't get my head around this..
I have 2 arduinos connected to each other using xbee modules ( no problem here )
I am sending characters H and L from arduino A to arduino B using code on arduino.cc/en/Guide/ArduinoXbeeShield
I am receiving the data with the physical pixel sketch and led on pin 13 lights as set in the sketch.
When i try to print the received data to an HD44780 lcd, i get numbers like 79 and 76 ( not the real numbers here ). What is happening here??
I've tried to seek information about dealing with this but with no luck :(
One more thing. How do i send ( human readable ) messages from arduino to another? Let's say i want to make some sort of a messaging thing.
I really appreciate if someone explains this to me or points to some good info!!
