RFID CARD READER AND FINGERPRINT- MY PROJECT- Week 11- 17
As a group, we have created an arduino project that includes an RFID Card Reader and a Fingerprint scanner. So the RFID Card Reader is used for making money transactions, proving a persons identity etc, and the Fingerprint Scanner reads the right persons data, for example if a person puts their finger on the scanner, it will read their data so then if they remove their finger and then put it back on the scanner, it will record the same data as it will be the same person. We connected both of these devices together and made an amazing project that works perfectly well.
There is a link below for users to click on that shows how the project works and everything we have used including the arduino. As a group, we made the video short so that no one gets bored and ends up doing something else.

ARDUINO NEURAL NETWORK- Week 21
A artificial neural system is a scientific processing model which is intended to impersonate the manner by which the brain responds to sensory inputs. The brain is comprised of a huge number of neurons which are associated with one another in colossal systems. So, I tested the neural network by plugging the arduino within the computer system to find a solution for running the neural network program. The solution was a number that was calculated by using the system above.
What is training for within the neural network?
Once a network has been structured for a particular application, the network i ready to be trained. There are two ways of training a neural network.
One way is called supervised training which involves a mechanism of providing the network with the desired output either by manually grading the network's performance or by providing the desired outputs with the inputs.
The second way is called unsupervised training is where the network has to make sense of the inputs without outside help. It also performs some initial charaterization on inputs.
Why is the XOR problem interesting historically?
The XOR problem is a classic problem in ANN research. It is the problem of using a neural network to predict the outputs of XOR logic gates given two binary inputs. An XOR function should return a true value if the two inputs are not equal and a false if they are equal.
There is some historical interest because it's the problem that Minsky and Papert used to show that there were some problems “perceptrons” (linear threshold units) could not solve, which people think triggered an “AI winter” during which it was difficult to get neural net research taken seriously.

THE BUBBLE BELT- Week 7-8
In the distant future, paranoid parents force their children to wear Bubble Belts. These force field generators allow children and teenagers to press a button, which would enable them to get into a bubble. They can also deactivate the bubble if they feel safe. In addition to this, the bubble constantly monitors the child’s surroundings, activating at the first sign of danger.
On a cold frosty afternoon, Rachel and her classmates decide to go on a hike adventure, in the terrifying, remote woods. While the class were on their hike, Rachel did not seem interested and wondered off alone into the woods. A few minutes later, she realised that she was lost and none of her friends were around her. She went in search for them, but to no avail. Just then, she began to hear spine-tingling sounds, coming from a distance so she quickly reached the button on her belt to activate the bubble belt.
As Rachel moves inside the colossal bubble, she comes across a dead end which makes her heart pound faster. As she tries to go back the other way, she encounters a terrifying wolf that has steel grey claws running at a menacing pace towards her and tries to attack her, however the fierce sinister wolf cannot break through due to the hard steel surface of the bubble. Just then, Rachel heard high pitch screams echoing through the trees and to her discovery it was an enormous bear with stocky legs and dark brown fur that suddenly pounced onto the wolf and attacked it viciously and killed it. It then approached Rachel with great force and strength and made a small crack on the surface of her bubble. As the bear was unable to break the bubble, he went another direction and Rachel sprints away from the bear.
Suddenly, she comes to the end of a steep cliff. Her heart begins to pace at an accelerating rate while she endeavours to look for solutions. She turns her head to the right and comes across an old, deserted house. As she cannot fit through the door with the bubble, she decides to deactivate the bubble belt. As she enters the house, she discovers dead, decomposed bodies all over the floor and starts screaming loudly. Then all of a sudden, she notices a large shadow on the floor and the next thing she hears is someone knocking relentlessly on the door, so she hastily runs up the stairs and hides in a cupboard. All of a sudden she hears her name being called, so she races down the stairs and opens the front door and to her discovery, it is her classmates. Her friends see the lifeless decomposed bodies scattered on the floor so they get Rachel and sprint as fast as they can. They leave the woods and inform the police. At last they were all reunited and in safe hands, Rachel tells her class mates about everything that she encountered in the ghastly, terrifying woods.

MIDI PIANO KEYBOARD ARDUINO- Week 3-6
The MIDI Piano Keyboard allows users to play different types of sounds using the MIDI notes. Back in the olden days, instruments were not accessible so a lot of people used the MIDI Piano Keyboard to play songs and produce different types of sounds.
In order to get the MIDI Piano Keyboard working, you must have the following:

In order to get the MIDI Piano Keyboard working, you must have the following:
- Arduino Uno Board
- USB cable
- Jumper cables
- 10k ohm linear potentiometer
- 1 tactile push button
The code helps to meet the standards of the MIDI Piano Keyboard project as it allows the users to play the sounds. If the arduino project did not have the right code it would not allow the user to make sounds on the computerized piano keyboard. This is why it must meet the MIDI specification.
I would recommend people to try this at home as it something interactive to do and everyone will be able to feel what it was like for the people back in the olden days.

RFID CARD READER- Week 3-6
The RFID Card Sensor uses electromagnetic fields to transfer data over short distances. In order to get the RFID Card Reader working you must have the following:
Some examples why RFID would be used is for making money transactions, proving a persons identity and many more. Having the right data on the RFID Card will allow a person to go through the right doors without any hassle.This type of project is very good for people who have credit cards/debit cards or any other type of cards that show identification it is you.

HEART RATE SENSOR-Week 3-6
The Heart Rate Sensor shows how quick your heart is beating. It is calculated by beats per minute and displays what the outcome will end up being. Above is an example of a heart rate test that has happened.

The heart rate sensor can be used in 2 different ways. One way is that it can be used as health sense so for example, if the persons heart is beating face then they can use it to see the results and hope the person calms down. The other way it can be used is in a fun way. For instance, it could be like a task to do in the class and everyone can try it to see what their heart rate is like and it would be a good laugh.
TIME OF FLIGHT DISTANCE SENSOR- Week 3-6
The Time of Flight Distance Sensor measures the distance of how long the light has taken to bounce back to the sensor. In the example above it shows a persons hand moving towards and backwards from the distance sensor. This proves that the Time of Flight Sensor can be very useful in the real world as many people would want to measure different types of signals including sound and light.

This was quite interesting to do as it allowed us as a group to try it ourselves. There is a video above to show people how this works when it is all set up.
