Hey everyone,
I'm thinking of making a project similar to this: Laser Harp
First of all I wonder which laser should I use ? I don't care about the color, I want to see the laser traces.
Also, I can probably split one laser beam into 5 or what ever using a mirror mounted on a motor and switching the laser on/off at the right moment, right ?
Also, How can I sense which laser is blocked ? use multiple LDR's or photo transistors ?
