IOT (Internet of Things) : Nowadays, devices connected to the Internet network are not that numerous. With IOT, every electrical device will be connected to the Internet network. ● IoT stands for Internet of Things. ● The concept is called IoT (Internet of things) that allows the user to control any device he is using. ● The major purpose of IoT is connecting physical devices to the internet ● The IoT is the network of physical objects connected via sensors, software, and other technologies. It links and exchanges data with other devices and systems over the internet. For example, smart devices can help turn on or off light. The IOT is a network that connects all devices having the following characteristics: 1. The device must be supplied with a WIFI connection. 2. It can be programmed from a computer 3. It contains sensors that make it interactive with its environment. Sensor (IoT hardware) is used to detect changes in the environment Advantages of IoT Disadvantages of IoT 1. Easy Access 1. Dependency on Technology 2. Quick operation. You can finish 2. Loss of Data many tasks very quickly because of the inflow of data 3. Data security , A lot of information is available on the Internet as it 3. Monitoring Data connects to all household 4. Following New Standards appliances THE ELEMENTS OF A SMART OBJECT: ● A Smart Object needs the following components in order to be connected to the IOT network. ● ○ A set of sensors considered as Input Devices. ○ An Internet connection to WIFI. ○ A Screen considered as an Output Device. ○ A MicroController considered as the brain of the device. A MicroController is an electronic board that links input devices to output devices. By linking the 3 components (MicroController, input, and output devices), you can obtain a Smart Object. ● Micro-Controllers are found everywhere: in the Car, in the Washing Machine, in the Fridge, in the Air Conditioner, in a Robot, etc. ○ THE MICROCONTROLLER SYSTEM: The diagram below illustrates the microcontroller system as a collection of parts or devices with three features: input, process, and output. A system accepts at least one input device, performs some action on that input, and produces one or more outputs. The definition of Arduino: ● Arduino is an open-source electronics platform based on flexible, easy-to-use hardware and software. ● Arduino is an electronic board considered as a Microcontroller that links the computer with all the components that can't be directly linked to the computer. It can be connected to the motors, the LEDs, the sensors, etc… ● With Arduino, it is possible to realize a prototype circuit to understand the IOT world more. ● Ardunio can interact with buttons, leds, smartphones, and sensors. ● The Arduino IDE is built on C/C++ language. Arduino components: ● A USB connection (USB socket) to link the Arduino board to the computer to: ○ Supply a 5 volt. ○ Download programmes. ● A 9 V for Battery power (Power socket). ● A series of [Digital Pins] from 0 to 13 = 5 volts ● GND=Ground, it is the [Digital Pin] that provides 0 volt. ● Power Pins ● Analogue Pins Tinkercad Tinkercad is an online platform that allows users to design and simulate 3D models. It is a free and easy-to-use tool that is designed for beginners and experts alike. One of the most exciting things about Arduino and Tinkercad is that they can be used together. Tinkercad has a range of electronic components that can be used to build circuits and control devices, and it also has a built-in Arduino simulator that allows users to program and test their circuits in a virtual environment. This makes it easy to prototype and test new ideas before building them in the real world. Creating the led circuit: LED Switch ON at the beginning, wait for 1s and then switch OFF.
