External G-Code control

I want to discuss how an external process like data from an Arduino can send and receive G-Code to Duet best. Examples are new sensors to control printing behavior (pause e.g.), timers to turn on /off LEDs at specified times, coordination of multiple printers by timing g-code execution etc.
Are those methods ok and are there other possibilities?
The firmware can accept commands received via USB, the Panel Due serial port, http and Telnet. So take your pick. If you don't have a Panel Due connected, sending commands through the Panel Due port is probably easiest. The signal level is 3.3V and the protocol is standard 8-bit asynchronous without flow control. The default baud rate is 57600.

Thanks a lot David, so there are some options.
