COA: Conor's Obfuscation Algorithm is a way of obscuring data being sent between an Arduino and a webserver. This is useful as most reversible encryption algorithms won’t run on Arduino and the very few that do are extremely slow. This algorithm can obscure most data on an Arduino in 100 to 300 milliseconds (It takes 400 milliseconds for a human to blink).

DPDK Optimisation & Analysis Tool

SEM

SEM: Smart Environment Monitoring system is an Arduino and web based (PHP) system that monitors, records and analyses environmental metrics both inside and outside (using external service) of the room that the Arduino device is located in.

SiteUp

SiteUp? is a php script and online control panel that sends an email if it can't reach a specified URL.

Servo-Position-Finder

Testing software to determine positions for a servo motor connected to an Arduino where the servo motor needs to be positioned very precisely.

EdgeOS-Throughput-Measurement-Tools

Python scripts for measuring throughput on Ubiquiti routers (running EdgeOS)

LEDPostBox

This project uses an Arduino Nano to add LEDs to a post box to alert the user to when there is post in the box

Humidex

The humidex (short for "humidity index") is a scale used to describe how hot the weather feels to the average person, by combining the effect of heat and humidity. (This is the Canadian Humidex not the American Heat Index).

FizzBuzz

This PHP code prints out a list of numbers up to the specified limit. But for multiples of three it prints “Fizz” beside the number and for the multiples of five it prints “Buzz” beside the number. For numbers which are multiples of both three and five it prints “FizzBuzz” beside the number.

ArduinoPowerUnit

This project is a power unit for an Arduino Microcontroller. The unit is supplied power using a 9V wall adapter and a 9V battery. When AC power is available the unit draws power from the wall adapter, when there is a power cut the unit seamlessly switches to the battery as a power source and back when power is available. During a power cut an LED is lit to alert the user that mains power is not available. There is also an LED to warn the user when the batteries are low.

Collatz

This PHP code calculates the number of steps it takes to perform the Collatz conjecture on a number. The Collatz conjecture is when you take any natural number greater than 1 and if n is even, divide it by 2 or if n is odd, multiply it by 3 and add 1. These steps are repeated until 1 is found.

Servo-Position-Finder-Using-Serial

Testing software that can set a servo motors position that is connected to an Arduino using Serial Communication.

Arduino-Speed-Time-Track

This project is a track that toy cars can race down. An arduino records the speed and times of each car on each run. The Arduino then sends this information to a Windows Application which records the data and draws a speed time graph. The software also calculates the acceleration of the car. The Arduino uses four LDRs and the length of the car to calculate its speed and acceleration. The Arduino uses LDRs to sense the light levels above the track, when a car passes over the sensor the sensor senses that it has gone dark and the Arduino times how long it is dark for. The Arduino then calculates the speed by dividing the toy cars length by the time taken to give the speed in m/s.
