Hi, @buzzzlightyear,
First, we can quickly test the grove Led , I’ll give you instructions
Step 1: Git clone the Github repository.
git clone https://github.com/Seeed-Studio/grove.py
Step 2: Execute below commands.
cd yourpath/grove.py/grove
then run python grove_led.py 5
after that, you can see the led connected on D5 start to blink, if it’s working please let me know.
