[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.

but luckily there are ways around it. [Stefan]’s solution was to make a hardware security module out of the newest ARM-powered Arduino Due. The build puts the secret key for [Stefan]’s AWS ...

With the Arduino Pro 4G Module, you can count on secure and cost-efficient flexibility for all your connectivity needs. Imagine deploying a fleet of autonomous drones equipped with the Arduino Pro ...

The Arduino powered Laser trip wire system project is currently over on the Kickstarter crowd funding website looking to raise $3,000 pledges to make the jump from concept to production. Patrick ...

In this project, we create a joystick-controlled laser by ... directly to Arduino pin 10, as shown in the circuit diagram in Figure 10-4. 3. Connect the GND from the joystick module to the Arduino ...

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 (blasts) the target using an inexpensive laser diode ...

HID Global announced the FARGO HDP 8500LE Industrial Card Laser Engraver, a new module in its FARGO Industrial Series for high-security state and government eID programs and other applications ...
