Time telling Instructions (you need these for binary watches)
Telling the time uses the colored LED's to represent hours & minutes. By looking at the 4 rows of lights, the Green & Red LED's at the top indicate the hour simply by counting them. 3 red = 3 o'clock.
The Bottom rows of green & yellow LED's indicate the minutes. 2 Green + 7 yellow = 27 minutes past. It's the same for the date mode to indicate month & date. The day is shown on the very top row of holes where the markings M, T, W show the day (Monday, Tuesday, Wednesday etc).
