A bit of explanation here.<\/p>\n\n\n\n

Firstly, this example program uses my device MAC addresses. If anyone else wants to run it, they will need to use their own MAC addresses.<\/p>\n\n\n\n

Secondly, I hate trying to keep track of two programs and what version of which program is in which device. Another worry is that a program is loaded into the wrong device. So to get things working here, I load the same program into each device and it tests the device’s MAC address in order to act a device 1or device 2. <\/p>\n\n\n\n

Thinking of a rainbow: red=1, orange=2, … each device changes color to show its device number, if its the only device turned on.<\/p>\n\n\n\n

If both devices are active, then each sends random numbers to the other and the number is used to switch to another rainbow colour.<\/p>\n\n\n\n
