Hi
I want to build something like this:Fade Away 1 - Matt Richardson, Creative Technologist
Now I wonder 2 things:
Firstly I'm not entirely sure how to control a laser with arduino. I can't find anything really good online. Say I wanted to hook up this laser: 532nm 30mW Green Laser Module 1 PCS | eBay
It has already got a module built in, so could I just hook it up like a dc motor? With + and - connected like in the first picture here: Motors 1
2) My second question is: How much power do you think I need. I would like to keep it as low as possible for safety reasons. Would 5 mw do the trick or do I have to go to around 30?
Thanks in advance
PS: I hope this is the right subform
