good morning everyonei am making a project in which there will be a large distance betwwen two aruino's
one of them will be a joystick which will take the orders and send them to the other arduino
this is an tutorial for it with arduino

and this is an a example code between two arduinos

i have a question about this code... i can only send one byte between each on and off operation? (transmitting enable and disable?)or i can send a whole byte?!
wiring between two arduinos
should there be a delay between each operation?
this is its pdf
