By pressing the particular location on the GUI, the loads can be ON/OFF remotely. So, this project gives the best solution with smartphones.Īt the receiver end a Bluetooth device is connected to the Arduino board, whereas at the transmitter end, a GUI application on a cell phone sends ON/OFF commands to the receiver. But, operating that switches to go near them is very difficult for the user. Presently, conventional switches are placed at different places of the house. As day by day technology is developing and houses are getting very smart. The main concept of this project is to design a home automation system using an Arduino board with any Android operating system based smartphone or tablet. in the evening and this process is frequent. At Last, the light intensity shuts down completely in the morning at 6 A.M and again restarts at 6 P.M. ![]() The light intensity is kept high during night time when the traffic on the roads decreases slowly and the light intensity also decreases increasingly until morning. The Arduino board comprises programmable commands that control the light intensity based on PWM signals produced. The lifetime of LEDs is more compared with HID lamps because LEDs consume less power. Arduino based LED Street Lights with Auto Intensity Control An Arduino board is used to control the intensity of lights by developing PWM signals that make MOSFET to switch a set of light-emitting diodes to get the desired operation. This project uses LED lights instead of HID lamps in the street lights. The main aim of this project is to control the auto intensity of the street lights using an Arduino board. LED Street Lights with Auto Intensity Control In this project, a servo motor, Arduino UNO & Ultrasonic Sensor (HC-SR04) is used. In this project, an ultrasonic sensor is used for determining the presence of an object within a specific range. ![]() This technology is applicable in missiles, aircraft, automobiles marine & weather predictions. Radar is one kind of detection system for objects which uses radio waves to establish specific object parameters such as its speed, range, position & speed. This project implements an Arduino based Radar Application through processing application. The list of Arduino projects for engineering students is discussed below. For a better understanding of these applications here we are explaining with an appropriate diagram. The applications of the Arduino board are mainly involved in Arduino projects that include obstacle avoidance, industrial appliance control, electric appliance control, intensity controlling of street lights, home automation, underground cable fault detection, solar street light, etc. Arduino Projects for Engineering Students The advantages of these boards include extensible hardware, inexpensive, simple, and clear programming environments. Most of the Arduino devices include the components like pins, power, reset button, TX RX LEDs, voltage regulator, and power LED indicator. The types of the Arduino board mainly include Arduino Uno, Arduino mega, Arduino LilyPad, Arduino BT, Arduino Nano, an Arduino Mini. The data of the Arduino board stored in data memory, whereas the code of the Arduino board is stored in the program. In the next section, I will discuss the specific data structure used by the card/tag to store information that we can either read or write to.Basically, an Arduino board employs the architecture of the Harvard due to separate memory for data and program code. ![]() The reader's antenna (in our case, the antenna on the RC522 is the embedded coil-like structure on the face) which will send out radio waves, which in turn will energize a coil in the card/tag (within close proximity) and that converted electricity will be used by the transponder (device which receives and emits radio frequency signals) within the card to send back the information stored within it in the form of more radio waves. ![]() The working principle of RFID communication is fairly straightforward. The card, on the other hand, contains a chip which can store information and allow us to alter it by writing to one of its many blocks, which I will go into more detail in the next section as it falls under the RFID's data structure. In the reader, there is a Radio Frequency module and an antenna which generates an electromagnetic field.
