I am fairly new to the Arduino/hardware scene. I decided that the best way to jump right in was to start a project.
I found a great one called a word clock, and theres already an existing project that can be found at http://www.dougswordclock.com/
I would like to use some RGB LEDs and make quite a large clock. My sketches at the moment use 26 groups of LEDs, totalling 130 LEDs all up.
I have the ability to wire it all up and construct the clock, however, I have no idea how I would control them!
At the moment, I am looking at wiring all the LEDs in a single circuit and using a relay on the grounds to control which groups of LEDs turn on. The relays would then be controlled by a couple of 8 bit registers.(TLDR;)My question is:
would this be an appropriate way to go about the project? Would there be a better way of setting up the LEDs and controlling them and is there any points that would not work/might cause me a lot of hassle.
Thanks in advance for your help!
