For bidirectional communications, Look up AlohaNet CSMA. You'll need to implement it yourself unless there a library already written for arduino. Unidirectional comms, just use a UART. |

I have a situation where I need two boards to communicate but there is only one data wire available between the two. Both systems are powered from the same battery so they have common ground. Is this possible with arduino-pico?
