I have this project where i use esp-now to trigger a function on a M5stack whenever i push the button on a M5Atom Matrix

it works very fine, but i want to add a feature that gives multible Atoms a command from the M5stack button so that button C starts a function on M5stack and sends a signal to multible Atom's to start another function.

It should be possible to add as many Atoms as i want with out adding additional code to the m5stack

Any ideas?

Here is the M5Stack
