Topic: wireless communication for standalone arduino (Read 764 times) previous topic - next topic


How hard would it be to create my own serial wireless communication "shield" for a standalone arduino? Has anyone done this? What would it involve? It would just be for arduinos to talk to each other. No need for WiFi.



Not hard and there are plenty of off the shelf solutions for this.  Many of the wireless modules are 3.3V so you need to do a bit of level shifting but other than that the modules are readily available.  I use these:


but you can buy them in shield form from this same vendor which handles all of the level shifting for you.
