Brainiac75 | LASER underpowered by its power supply? | First TTL/PWM Arduino attempt @brainiac75 | Uploaded February 2024 | Updated October 2024, 3 days ago.
My yellow-green laser module is not even close to performing as advertised. Perhaps because the power supply is less powerful than advertised too?
In this video, I max test the power supply and see if it matters.
I also build a pulse-width modulator using an Arduino Uno in an attempt to adjust the laser's power output. Will I succeed?
