We can use them to cut things, create laser light shows, and also as a rangefinder. [Ignas] wrote in to tell us about [Berryjam’s] AMAZING write-up on creating an Arduino based laser rangefinder.

[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… ...

LaserControl 🔴 — Arduino 12V Laser PWM Controller A professional single‐file Arduino sketch to safely drive and dim a 12 V laser module using PWM, a MOSFET driver, a potentiometer and a toggle button ...

Arduino-Nano-Laser-Demo A simple example of using Arduino basic GPIO pin HIGH and LOW to switch on and off some cheap Chinese red lasers. This demonstrates the most simple aspect of any ...

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.

The purpose of this module is to create a cat toy that moves a laser with random motion. We will then use a potentiometer to control the speed of the laser. It ultimately provides a good introduction ...

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 ...

Arduino has just launched a “Plug and Make” kit designed for beginners with an Arduino UNO R4 WiFi board, several “Modulino” modules, a “Modulino” base to neatly attach the UNO R4 and modules, and ...
