Hi,
I want to hookup a Grove LED to an Arduino without using a base shield. Which of the wires (red, white, black and yellow) should I connect to which pin?
Cheers,
Dear,
you know,red means power,black means ground,white means “no connecting”.
At last,yellow means SIG,so you can conncet it to your Arduino Digital I/O pin(0 -13pin).
Enjoy it!
