I have an Arduino Uno connected via usb to my oPi One running Node-Red 1.2.6. The Arduino runs a modified Firmata example sketch and I use node-red-node-arduino to send/receive data to/from the Arduino etc. Is it difficult to use Node-Red to upload a new sketch binary instead of having to plug the Arduino into my desktop each time?
I'm thinking there's two components to solve here:
1st: How to get the binary onto my oPi or how to retrieve it.
2nd: How to do the actual upload. If there's no existing, convenient node for that then I think I'll just keep doing what I'm doing.
