Laser Blaster Last Updated: 7/27/18 Teaching Standard: In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates ...

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk.

Emit high-coherence light at telecommunication wavelengths; Allow laser-frequency tuning at record speeds; and is The first narrow linewidth laser with fast configurability in the visible waveband.
