Maker Faire is coming up in a few months, and as part of a possible=20 project I need to control about 6 devices moving on a platform. I'm=20 considering either IR with an overhead TX, multiplexing the signals and=20 each device selecting only the part of the message they want, or the=20 nRF24L01+ devices which are really low-cost now. My concern with the=20 nRF24L01 is interference. I just ordered some to tinker with, but=20 having not used this yet, I'm not sure how exactly they work and if=20 they'll be susceptible to interference from the various WiFi networks=20 and the possibility of others possibly using the same device for their=20 projects. Anyone with experience on these know if I should not choose=20 that path?
