Given there was a powerful laser bouncing around with mirrors, a plywood box formed the enclosure. The stepper controller is an Arduino Mega running the Marlaser firmware, though [Owen] admits ...

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.

Laser ranging has many applications in production and life, such as ranging, positioning, obstacle avoidance, and so on. Time-of-Flight (ToF) ranging, as a type of laser ranging technology, is often ...

In this project I have designed Laser Security System Using ... Example: At indoor light the sensor will give a value of around “750” when using the “analogRead” function while using Arduino it’s ...

You are after the stepper motor ... insert the laser into its holder on the laser engraving machine. Make sure it is snuggly, and firmly, held in place. Now, grab your Arduino Nano and the ...

The project utilizes an Arduino board, rain and sunlight sensors, a stepper motor, a stepper motor driver module, and a chain drive mechanism to control the opening and closing of a door based on ...

Les built a rig that scans the laser across the sensor using stepper motors. Les describes the rig as something like a CNC machine. In the video below, you can see close-up footage of the process, ...
