COM PORT - Theater

Projects Networking, Protocols, and Devices

Hello... sorry if i create new topic which already exist, but i realy couln´t find it.

I am using Arduino Mega inside puppet for theater show.
In one point during show, i connect this puppet via USB to my PC.
Its controlled by Pure Data, - Standard Firmata.

Problem is that i have to connect and disconnect this USB several times during show, and it has to happen fast. which is fine until Arduino change it´s port. Sometimes its PortN.7 and sometimes PortN.11. And there is no time for re-writing port number.

Is there way i can save this Arduino on just one port?

I am not really pro and sorry if its stupid question, but i would be really glad if you could help me.

Thank you for any answer.

Why do you have to unplug it? Would a usb hub solve it?

3

Because its inside puppet and i have to play with it.
Only parts of show needs cable and in other parts of show cable there is obstacle.

Maybe communicate with the PC using Bluetooth?

No space for Baterry, the cable has meaning in that play.

I realy need what i asked for ... sorry and Please ...

Thank you :slight_smile:

Use an external USB to serial adaptor that is permanently plugged into the computer. You only need to run the Gnd, Tx, Rx and 5V wires to the Arduino. Disconnecting and reconnecting those 4 wires with not affect the USB COM port assignment.

That's what happens when a committee designs a cheap consumer standard. The assumption is that the firmware in the connected device contains the unique ID rather than the interface chip itself.

Remember, this is the same committee gave you the USB 'A' type connector, that's the rectangular one you have to plug in 3 times because you cannot tell which way up it's supposed to be.
