I’m relatively new to Arduino. I have successfully done a couple of projects, one involved implementing an H-Bridge for motor control. I’ve been casually tinkering since I was a kid, so my knowledge is at a beginner/intermediate level.
Here’s my situation. I need to make an awesome Valentine for my wife (long irrelevant story), so as a part of it, I wanted to make a sign with dozens of red LEDs that chase in different patterns. My original thought just to use all 16 digital output pins and turn them on/off in order to achieve the “chasing” effect. I would hook them up to the LEDs in each symbol/letter different orders to achieve different patterns, but each pattern would have to be limited to the 16 pin sequence. I’m not sure how efficient that is. I’m also not sure if I can even hook that many LEDs up in parallel. Or would I hook them up in serial?
The design would be simple. Probably: heart BE MINE heart or something similar. Perhaps a heart with the word LOVE inside.
Anyways…I have two questions:
- What’s the best way to hook up so many LEDs? Solder wires directly to the LED leads? I wouldn’t even know where to start with this.
- Is there a different approach to hook up and “chase” this large quantity of LEDs I should/could use that I’m not aware of because of my lack of experience?
Any and all help appreciated! I have an Arduino Duemilanove.
Thanks for the help!
