Here’s the version of his laser engraver” DIY laser engraver components list : – Arduino Nano – 250mW 650nm Laser Module – A4988 Motor Driver – IRFZ44N Mosfet – LM7805 Voltage Regulator.

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk.

This module allows you to develop a timing system, which utilizes the Arduino’s fast internal clock to provide an accurate timing system for kinematic experiments. Also, this module focuses on how to ...

Last Updated: 7/27/18 Teaching Standard: 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 ...

The laser tower is glued to an Arduino board and attached to a laser module, all enclosed in an old Altoids box. The tower is composed of two SG90 micro servos, attached to a pan / tilt camera ...

You'll need an Arduino, of course, and you'll also need a pair of laser pointers, a few servos and motors to make the lasers move as time passes, and of course, the IKEA BLANDA salad bowl ...

The little laser pointer was replaced with a 200mW laser module, the hexagonal mirror mount and case were 3D printed, and the mirrors were painstakingly aligned so the laser sweeps out a plane.

That’s when I saw several instructables (Laser Tripwire Alarm, Arduino – Laser Tripwire Alarm System, and Super Easy Laser Tripwire, among others) using a laser tripwire.

When the Arduino senses a state change from one of the photocell, meaning the beam of light has been interrupted, it plays the appropriate wave file stored on an external JQ6500 sound module.
