So there are several options including radio frequency and Bluetooth but both seem slow. I need a wireless way to communicate between two arduinos. The values i need to send don’t matter i will choose after finding a good solution. The arduinos will at any given time be no more then 6” apart however one is spinning. The delay between signals should be a few microseconds or less because i really need it fast. Leave some names and ill do research

  • Please update the title, add "wireless". I think the nrf24L01+ will do. – Jot Aug 30 '18 at 18:51
  • IR, maybe IRDA would be the fastest native way. – dandavis Aug 30 '18 at 18:53
  • BT isn't slow, it just has a higher latency. – Gerben Aug 31 '18 at 13:32
