Advice Column 5 years, 3 months agoHi Everyone, we are a new team out of Marin. Are there any scrimmages to sign up for in October in the North/South/East Bay? We cannot host one (we have no idea what we are doing) but it would be great experience to go to one.

1) What is the color sensor reading specifically?
2) What is the color sensor comparing values to?
