Connect the breadboard rails to Arduino GND and +5V ... tape if you want something more temporary. Now you can control the laser using the joystick. The servos will clip into the tilt-and-pan ...

Nope, of course not! [Guido] built it with a unique control box, two Arduino 2560’s and an Xbee to communicate between them. He was told to design it using old and new technologies so he’s got ...

[Rich] over at NothingLabs has put together a really cool laser ... to the Arduino, which it now uses as a pulsed power source. Once he had everything built, he positioned the laser using a ...

Powered by an Arduino Uno, this laser tripwire alarm project works ... The idea behind this project is to build a lightbulb controller using a light-dependent resistor (LDR).

Laser cutters are great DIY tools, but they're pretty expensive. If you'd prefer to build your own, Instructables user SilverJimny shows you how using an Arduino. The build here uses an Arduino ...

Just follow the schematic diagram to complete the construction, and use any standard 9VDC Arduino power source to energize the system. Here, for demonstration, three different color LEDs (Red, Green ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...
