Hello everyone, I was given a project by my work (intership), the project consisted of me creating an Array of LEDs that portrayed a title (in this case, school Title), that will blink in a sequence at a very fast pace. So my school name is pretty long (21 characters), so i design or actually sketch a simply drawing of how the LED will represent the title, i manage to get it to 205 LEDs (big project).
Anyways, originally i wanted to use the Arduino Uno since i found it a lot easier since i can do all the coding (C) and simply uploaded. However, i realize that the Uno does not have enough output to present the LED's HIGH's and LOW's. I read about charlieplexing and was intrigued. However, the formula given (n^2 - n) made me realize that i will not be able to get no were near 205 LEDs with a single arduino. So what do you guys think? what perspective can you guys give me or hints! I'm a student so my knowledge isn't extremely amazing but i do know my basic well, etc. Also would it be best of if i just use the Atmel AVR chip that the Arduino Uno use instead of using the Arduino Uno?
