Passive Infrared Sensor(PIR) is a device that can detect infrared radiation that is emitted by its surrounding objects. Also, this sensor is mostly used in home security system and as well to activate interior lighting when someone enters the room. In Arduino, the hardware required are: - Arduino Uno - HC-SR501 Passive Infrared Sensor - Jumper Wires - LED These PIR sensor consist of 3 pins(VCC, Ground pin, and Output pin in the middle). Firstly, connect VCC of PIR to Arduino 5 volts. Then, connect ground to ground pin and output pin of PIR to digital pin number 3 of Arduino. Also, place the LED positive leg to pin 13 and negative leg to GND of  Arduino.               Code: /the time we give the sensor to calibrate (10-60 secs according to the datasheet) int calibrationTime = 30; //the time when the sensor outputs a low impulse long unsigned int lowIn; //the amount of milliseconds the sensor has to be low //before we assume all ...

  Recommender System: Recommender Systems are the software agents that elicit the interests and preferences of individual consumers and make recommendations accordingly. It is the system used according to the user based preferences and most of them are from online stores providing recommendations. There are two basic approaches of Recommender System. They are: Collaborative Filtering: This filtering is used according to the model based, which might have a single user behaviour or from other users who has the similar traits. The collaborative filtering is mostly used as group knowledge to form a recommendation based with like users. Advantages of collaborating filtering:  - It can be used by large , commercial e-commerce sites and applicable in many domains. - It uses the wisdom of the crowd to recommend items. - The users give rating to catalogue items and some customer have similar taste in past, will have the similarity in future as well. Disadvantage of collaborative filter...

  Activity 1 - Real Users For the following pictures decide what existing or fantasy input/output devices would benefit them. Remember people have five senses sight, smell, taste, touch, and hearing, so you might want to create devices for each of them – there is also the possibility of direct brain input.             According to the pictures, these might be the input and output devices that would benefit them. A corporate worker, telephone operator: Input Devices: Computer Keyboard:  Used for typing and entering data. Mouse or Trackpad:  Enables navigation and interaction with graphical user interfaces. Scanner:  Used to convert physical documents or images into digital format. Touchscreen:  Devices, such as laptops or tablets, having touchscreens for direct interact. Barcode Scanner:  Common in inventory management or asset tracking. Biometric Devices:  Such as fingerprint scanners or facial...

MIDI is a Musical Instrument Digital Interface, which is used to control the synthesizers, sequencers and other musical devices. In Arduino, the hardware required are: - Arduino Uno - Bread Board - USB Cable - Wires - LED - Midi to USB - B10k Linear potentiometer At first connect the Arduino to pc with the help of USB then connect the Midi to USB with Arduino. Also, attach the potentiometer to the breadboard and with the help of wires connect it with the Arduino as well as connect a LED to the Arduino. Then, from the Arduino example go to communication and use the Midi code: Code: void setup () {   // Set MIDI baud rate:   Serial . begin ( 31250 ) ; } void loop () {   // play notes from F#-0 (0x1E) to F#-5 (0x5A):   for ( int note = 20 ; note < 72 ; note++ ) {     //Note on channel 1 (0x90), some note value (note), middle velocity (0x45):     noteOn ( 0x 90 , note, 120 ) ;     delay ( 100 ) ;     //Note on channel 1 (...

         Case Study: Smart homes for older people with disabilities Dilemma - Part one: You are the software engineer responsible for the integrity of Ferndale's system. During a routine inspection you discover several indicators suggesting a data breach may have occurred via some of the smart appliances, many of which have cameras and are voice-activated. Through the IoT, these appliances are also connected to Amazon Ring home security products - these ultimately link to Amazon, including supplying financial information and details about purchases. 1. Activity: Technical analysis – Before the ethical questions can be considered, the students might consider a number of immediate technical questions that will help inform the discussion on ethical issues. A sample data set or similar technical problem could be used for this analysis.   For example: Is it possible to ascertain whether a breach has actually happened and data has been ...
