This is a great addition to the Arduino workshop. The only issue I am having is with the communication processor used on the UNO . My MAC won't recognize it. I am working with Apple as they seem to have taking the su account from us and the sudo nvram boot args kext dev mode 1 won't execute. Ater 1/2 hour with them I am installing mojave on the system ( per their request) now and will look in to the issue some more. Obviously a MAC thing and not an issue with the kit. Just mentioning it for other MAC users.
Very busy. Difficult to find time to solder and write sketches, etc.. Sliw going. But, it looks, will write again when experimenting...
