(yes I'm new, like many)
Idea: Create a sketch on my computer, load it to Arduino Uno. Check if it works If it works, I want to unplug the USB, walk to my (indoor garden) and run the sketch on the Arduino without being connected to the USB. (and maybe be connected to Wifi, via a shield; but that is second part of question)
So question is:
Can it be done?
Should I: 1. Connect via USB 2. Load/setup/test sketch 3. Run on Arduino 4. Connect to external power source (in parallel?) 5. Unplug from USB 6. and walk to garden ...?
Hope somebody can help.
