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 ...

Makers and electronic enthusiasts searching for a small laser sensor may be interested in a new Indiegogo crowdfunding campaign which currently has 19 days left to run and is raising money to take the ...

Panasonic has produced a range of micron-accurate industrial distance measuring sensors. Unlike its earlier similar sensors, digital output devices in the new HL-G2 series include interfaces for both ...

[Neumi] wrote in with a sweet robotics hack. It’s a 2D laser distance sensor (YouTube) made with a cheap line laser and an optical mouse’s flow-sensor chip used as a low-resolution camera. In one ...

Precision sensor supplier Micro-Epsilon has extended its non-contact laser distance sensor portfolio with a low cost unit that is even more robust and compact than its predecessor measuring distances ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer. The following is excerpted from the ...

If you have ever wanted to create your very own laser tripwire grid like in the movies to protect your valuables possessions, buildings or outhouses. You might be interested in a new Arduino ...
