A laser diode finds applications in CD/DVD reading and recording, optical-fibre communications, laser printing and scanning, laser pointers, directional lighting, barcode readers and so on. A laser ...

Laser Diode Positive Pin (+) → Connect to 5V pin on the Arduino. Laser Diode Negative Pin (-) → Connect to GND on the Arduino. LDR (Light-Dependent Resistor) Connection: LDR Pin 1 → Connect to 5V on ...

I suggest you switch out the a 12x 405nm diode. Run it at around 400ma. Its single mode, the wavelength is absorbed much better than red by most materials, and it will be higher power than this diode.

2 * Arduino Uno or similar. (anything with an analogue read pin will probably work) LDR (light dependent resistor) 10k ohm resistor; a laser diode; Using the wiring diagram, assemble the circuits for ...

Arduino 13 Note Midi Laser Harp (video) 3:05 pm May 5, 2016 By Julian Horsey. ... The laser diode was synchronized with the galvo using the Arduino.

The Arduino illuminates (blasts) the target using an inexpensive laser diode mounted on a servo motor. Interesting applications of applied math include computing distance based on sonic travel time, ...

A 2*2 optical self-routing switch using integrated laser diode optical switches is proposed. The switch is composed of a Benes network, which can perform large-scale switching functions using less ...

Here’s another Star Trek phaser toy with a laser added. [Jay] started with a 1994 Star Trek phaser and added a 12X Blu-Ray diode. The sound effects of the toy still work, a nice touch that yo… ...

An integral, long-lifetime, laser diode-triggered 50 kV/10 kA gas switch based on a kind of fast named light-initiated multigate switch (LIMS), is described in this article. The principle of this ...
