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.

A rotating machine that is controlled by a robotic glove. Neverending fun. Step 1: Concept Our seminar assignment was to design a useless machine. Thinking about absurd tasks, we were inspired by the greek myth of Sisyphus and the idea of gravitational weight shifting in an endlessly repeating mechanism. We wanted to add user control

Are you fascinated with the passage of time? Do you want a stylish, modern and functional timepiece to add to your clock collection? The word clock is a one-of-a-kind time telling device, using a grid of letters to spell out the time. While you could spend thousands of dollars on other versions of this idea,

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
