Arduino Laser Turret, Overview: In this endeavor, I will show how to construct an Arduino laser turret with servo motors and a two-axis joystick. I will supply the code needed along with a circuit diagram, along with a thorough explanation of the project. This will allow anyone to construct the laser turret without facing any […]

1. TRYING TO MEASURE THE SPEED OF LIGHT WITH AN ARDUINO We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. Last month we saw [Udo]’s blinkenlight shield that can be used as a line scan camera. It’s a neat piece of kit, but [Udo] really wants to
Meet Chartreuse! Chartreuse’s face follows you when you walk by. When she sees you, her eyes turn yellow and she gets a happy expression in her eyes. As you walk away, her eyes change to blue and she sadly turns away. Chartreuse is powered by an Arduino Uno, two servos, and a stepper motor and
Laser harps are musical devices with laser beam “strings.” When the beam is blocked, a note is played by the instrument. Usually laser harps have the beams travel vertically in the shape of a fan or vertical lines. In this project, I built a laser harp with stacked laser beams that propagate horizontally. The beams
A couple of weeks ago I presented my culmination project, framed laser harp, at New York City College of Technology. Work on it was so interesting for me, that I decided to share it here. I am an Arduino amateur and don’t have any professional experience in electrical engineering or programming. Neither am I a
The AFBR – S50 is a multipixel distance and motion measurement sensor. It has an integrated 850nm vertical cavity surface emitting laser (VCSEL) which uses a single voltage supply of 5V. It’s measurement rates are quick and as fast as 3 kHz, which is a distinguishing feature. However, this is not the reason why the

The idea of using triangulation for distance measurements is well known since Pythagorean time, when his brilliant formula become available for mathematicians. What is new in this design, is lasers power control via “blooming” effect of CMOS camera. Here this “negative” effect was put to work instead of ADC. No need high price “no-blooming” camera!
I enjoy creating sumo robots and am constantly searching for innovative sensors and materials to improve the speed and intelligence of my robots. I discovered the RPLIDAR A1, available for $99 on DFROBOT.com. I mentioned my interest in testing the sensor, and they offered me the opportunity to test it out. Once I obtained the

1. Introduction & Background Theory 1.1 Objective The objective of this project is to research, analyze, design, fully implement, and program an Arduino Uno microcontroller board to achieve PI control of the output power of a laser diode. Laser diodes require variable current sources for operation, as the current must be adjusted to maintain linear

A laser security alarm stands out as a highly effective system designed to detect any object or individual’s presence. Within a designated room, multiple laser beams are often employed. Reflective mirrors are commonly utilized to create a laser grid. When any object intersects these beams, triggering contact with the laser, the alarm system activates instantly.
