An impressive persistence of vision laser projector built using an Arduino and a hard drive case has been demonstrated by a DIY enthusiast. The device uses a circular array of rapidly spinning mirrors ...

[over9k] used his Arduino to set up a laser trip wire. The laser is mounted along side the Arduino, reflects off of a mirror, and shines on a photoresistor that interfaces via a voltage divider. Th… ...

There is a grbl control board which is made up of an arduino/atmega microcontroller and some motor driver (usually a4988 or drv8825). This board receive GCode commands from LaserGRBL and produce ...

A laser projector creates a light show that seems to be coming from dozens of laser beams. It only needs a single laser beam to create the effect because the beam is diffracted as it emerges from the ...

4. Connect the breadboard rails to Arduino GND and +5V, and then check that your setup matches that of Figure 10-3. Mounting the Laser. For this project, I’ve attached the servos to a pan-and ...

A laser diode can be interfaced with Arduino Uno using photoresistors, photodiodes, phototransistors or similar sensors and detectors. Fig. 1: A laser pointer. Laser diodes and modules are available ...
