Connect 2.4Ghz Nordic NRF24L01+ transceiver to Arduino and run the pingpair_ack example sketch from the RF24 library. A pair of these will communicate over a range of approx 10-20m indoors with 2 concrete walls in-between. Range outdoors is approx 20-40m. The scanner sketch is also useful to find free channel in heavy wifi traffic.
so, I'm working on a project and decided it would be nice to have a small pcb for me to work on the communication between two atmega microcontrollers.
I designed as a very small development board with a UART connector to debug the RF24 communication but also so the whole board can be used as a shield, after.
My intentions are that, after I manage the RF stuff, I can use the board to input data...
