HI! I will describe my project briefly:
I have a strip of leds (WS2813) and I'm making a multifunctional RGB lamp. This led stip is attached to an arduino. It's just supposed to receive data and light the stip.
I want to control it using some potentiometers (to change colors, brightness, number of leds to light etc), and some buttons (to change modes, to change the temperature of the white and so on).
This is supposed to be controlled by the other arduino with the HC-05 module in master mode.
The issue is that apparently I can send only one char type variable while I have at least 5 integers to send.
Is there any solution for this kind of problems? Any library that I can use or different module that can send more data at once?
