This is my first Arduino project. I want to have 10 laser diodes (6mm, 5V, 5mW, each have just a red and blue wire and act like a simple laser pointer: link to the ones I’m using ). I need to be able to turn each one on and off independently of the others. I also want a bluetooth controller so that I can send commands from my Android cellphone. Thinking the HC-05? Want to go with the cheapest Arduino, so that I might be able to produce them in more bulk and still be affordable.
I’ve read comparison charts, but not really sure how many digital i/o and analog inputs I’d need for this. Would an Uno R3 do the trick, or if not perhaps a Leonardo?
Also, outside of the power supply and a case, is there anything else I’d need for this?
