Setting up wireless communication between two Arduinos
Here, I’ve used an Addicore Tranceiver Module to establish a wireless link between Arduinos. First, I wired the two modules to their respective Arduino Nano boards. Then I uploaded the proper libraries to the Arduino IDE, and I finished by uploading the ‘Send’ Code to one board and the ‘Receive’ Code to the other.
All ‘nerdery’ aside, what’s so special about this?
- The hardware is pretty cheap – I got the Arduinos for about $3 each and the tranceivers for about $7.
- The software is open source – so there was no direct cost.
- This turns into a general purpose ‘WiFi remote control.’
Possible applications can include activating warning lights without installing electric lines, motion detection notification without having to buy the whole security system, or creating a wireless doorbell. And while all of the above items can be searched for and purchased, the items can’t be custom configured like this setup.
