I'm fairly new to Arduino and I would like to recreate something like this
I'm currently reading a book on Arduino for dummies. It's very helpful to me as I don't have a lot of background with this sort of thing. I'm just a bit lost as to what things I'm going to need to get this started.
It also doesn't help that the videos is in Spanish
However I'm confident that I can somehow recreate it.
If anyone out there can give me a start and tell me what sort of things I'm going to need, I would be very grateful!
Don't put too much stock in that second video - the one using 74hc595 shift registers to drive 8x8 matrix. It can be done and is a useful learning excersize, but you would not do that for a real project.
The chip for this job is called max7219. You can get pcbs that attach to the back of each 8x8 matrix, and attach to each other in a chain. Each pcb contains one of these max chips. The Arduino needs only to be attached to the first in the chain to control all of them. Have a look on eBay or Amazon.
You will need a separate 5V power supply for your project. The Arduino's 5V output can drive one 8x8 matrix, maybe two, but no more than that. When you have an 8x8 matrix working, you can light all 64 leds at maximum brightness and measure the current that uses to work out how much current will be needed in total. The psu must be regulated or switch-mode. You can run the Arduino from that same supply.
