TTYL vs Analog

[landshark]

Are there real benefits to using a laser via Analog rather than TTYL?

Definitely. TTL only allows a laser to be turned on or off. With Analog control you can change how bright the laser is (assuming your laser modules support it). This is especially important if you want a full color projector.

If you can only turn on and off a red, green and blue laser you can get 7 total colors. That's it!

With an analog setup the number of colors and brightness settings would be calculated by the number of analog "levels" per color.

That makes sense. Thanks!
