How do you make a 12x1 LED Matrix?
I'm completely new to this site as well as DIY projects so I would love some help on a uni project I am currently trying to start. My idea is to make an abstract clock which only contains an hour hand only and the clock face itself will rotate to tell the hour. The hand will be made up of a 12x1 LED matrix. Each light is supposed to represent each 12th segment of the clock and will light up when it is past that segment in time. For example, at 3:15, the clock face will have rotated so the hour hand (that always points up) points on the 3 and 3 out of 12 LEDs will be lit. This has to be programmed with an Arduino.
Being new to physical computing etc. I am so stuck on how to even begin this project! If anyone has any ideas of how I can begin this please let me know! Or just help me get started by telling me how I can make a simple 12x1 LED matrix to act as the hour hand. I look forward to your replies, many thanks everyone!
