Hello,
Me and my friend are making a robot.The problem is that he works with atmega8, while i have arduino uno based on atmega 328. my question, can we transmit data b/w them?
the arduino uno will be on the transmitter side with the atmega 8 at the reciever side or vice-versa. we will be communicating through RF.
what will be the circuit and coding??
any help is appreciated
Regards,
Shubham
While you can connect the two chips Usart ports direct to each other to test your comms link, as you can see from the Uno circuit diagram use 1k resistors in series in each line, this stops any short should you connect the lines the wrong way round.
With the modules I mentioned in my last post, you can communicate with those wireless modules through UART or SPI.
I assume you know how to use UART (serial port) in ATMEGA.
