So I got two HC-05 modules (ZS-040) and successfully paired them, thanks to Martyn Currey (Arduino with HC-05 (ZS-040) Bluetooth module – AT MODE | Martyn Currey). Yes, they blink in synchronicity. Now I have a bunch of sensors. Just assume they are potentiometers. I want to transmit the raw analog input from one Arduino (Leonardo R3) to another Arduino (Due). How do I send and receive data using Bluetooth. Help me out with setup and code. Thanks in advance.
