hihi....im trying to send a character 'a' from PIC to arduino UNO then based on that light a LED in arduino port.
i will use cheap wireless 433Mhz module transmitter and receiver.
transmitter = Cytron.io - Simplifying Digital Making
receiverhttp://www.cytron.com.my/viewProduct.php?pcode=RF-RX-433
So question is, what is the best way to communicate between PIC and arduino UNO.? anyone interface these two before wirelessly?
