Aurac Posted November 27, 2019 Report Share Posted November 27, 2019 I want to make 2x arduino talk to each other via rf and using sensors. If 1x arduino detects an obstacle it sends a signal to another arduino to lyt a red lyt, if the first arduino area is clear it sends a signal to the 2x arduino to switch the red lyt to green. This is to be used in a railway station, were arduino 1 is in the station arduino 2 is on the approach to the station, if 1 has a train then 2 is red, if no train in 1 area then 2 can proceed to station. I hope that is understandable to you. Plz try to help. [email protected] Quote Link to comment Share on other sites More sharing options...
HarryA Posted November 28, 2019 Report Share Posted November 28, 2019 If you search on amazon.com for "arduino rf" you will find various transmitter - receiver options. Like this for example> https://www.amazon.com/WHDTS-Transmitter-Receiver-Transceiver-Communication/dp/B07L8RXSDF/ref=sr_1_36?keywords=arduino+rf&link_code=qs&qid=1574902183&sourceid=Mozilla-search&sr=8-36 for this model note: T400 Transmission Distance: 400M T400 Receiving Distance: 50M GWB Transmission Distance: 400M GWB Receiving Distance: 400M I do not see the differences between the T400 and the GWB units when ordering the units.
