Objective and Background <> Objective: The gift of sight is precious; that is why we tried to model an artificial retina with the properties of color detection, saccades, and pursuit tracking. Structure of a Retina: A retina lies in the back of the eye and consists of a layer of photoreceptor cells called rods and […]

Our final project moves and clicks a mouse cursor on a computer screen by tracking where the user’s eye-movements using infrared eye-tracking technology and a gyroscope. The motivation for this project came from thinking about applications of infrared technology. We narrowed our ideas down to eye-tracking because of its potential benefit to the disabled and

One way to extend the functionality of the micro:bit is to use a board called moto:bit by SparkFun Electronics (approximately $15-20). It looks complicated and has many features, but it isn’t hard to run servo motors from it. Moto:bit allows you to run more powerful motors than the tiny micro-motor that you can run from the micro:bit

Introduction For our ECE 4760 final project, we implemented an interactive CPR training dummy which can coach the trainees through the CPR process with a LCD to display instructions. The prototype CPR training dummy built is a budget-friendly one that contains a re-programmable Atmel ATmega1284 microcontroller and other hardware components so that it can interact

Ever wanted to know how much solar power you could yield by putting PV cells in a specific place on or around your house? This Instructable shows you how to build a data logger based on an Arduino (or Genuino) Uno with data-logger-shield and a PV cell recording the electric power yielded during a sunny

In this tutorial we’re going to play with a gesture sensor (APDS-9960) and a neopixel ring to learn how to combine them both using an Arduino UNO. The end product will respond to left – right gestures by animating led movement right or left, and to up-down gestures by changing leds color.

Calculating on paper is never an easy job. And when it comes to formulas with sub-formulas of their own, it is nothing short of a nightmare! Take the case of a simple pendulum, which has a variable with a formula of its own. What if there was a way to replace these scary calculations with

Let’s measure distances with an ultrasonic rangefinder (distance sensor) and Arduino’s digital input. We’ll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. You may have already learned to read a pushbutton and PIR motion sensor with Arduino’s digital input,

My project is to make a heel (shoe) that senses when your foot is tired and then eases the pain. I will have a force sensor measure how much pressure is on your foot for 3 minutes. If the pressure is at a certain measure for 3 minutes, then a vibrator will go off and
