Tell us about yourself!
Not being familiar with fritzing diagrams, I guess that I mistook what is the power in icon to be the laser, and I assumed that the diode icon was indeed an LED , whereas in fact I now realize that it's the laser . So now I have things straightened out (maybe)Sorry for being dumb :-)
Did you ever sort out where the power supply is connected? Several people asked this question, but never got a reply , and I have the same question. Is everything - laser, Arduino, motors run from the same power supply?
