    ARDUINO

                     Arduino is a small electronic board that can follow instructions to control things like lights,
                     motors, sensors and more. It is like a tiny computer that helps you build smart devices. You
                     write code and the Arduino board reads it and makes things happen—like turning on a light or
                     moving a robot.
                     The following are the types of Arduino boards:

                         Arduino Uno: Arduino Uno is the most popular and beginner-friendly
                        board.  It is easy  to  use and perfect  for  simple  projects  like  blinking
                        LEDs, sounding buzzers or building a basic circuit. Most students start
                        learning Arduino with this board.

                                                       Arduino  Nano:  Arduino  Nano  is  a  smaller version  of  the  Uno.
                                                      It works the same way but is tiny, which makes it perfect for small
                                                      or portable projects. It can also fit on a breadboard, which helps
                                                      in building neat and compact circuits.

                         Arduino Mega: Arduino Mega is larger and more powerful than Uno.
                        It has more memory and more pins, which means you can connect
                        many sensors, motors or displays at once. It is often used in bigger
                        projects like robots or home automation systems.

                                              Arduino Leonardo: Arduino Leonardo is special because it can act like a
                                              computer keyboard or mouse. This means you can use it to build devices
                                              that control your computer with buttons or sensors, like making your own
                                              game controller.

                         Arduino  LilyPad: Arduino  LilyPad  is  a  round  and  soft  board  designed
                        especially for wearable projects. You can sew it onto clothes and connect it
                        with special thread instead of wires. It is perfect for making smart clothing,
                        light-up costumes or wearable gadgets.

                     In Tinkercad, Arduino is a virtual version of the real Arduino board. It allows you to build and test
                     your electronic projects on a computer screen, without using real wires or parts.

                            COMPONENTS OF ARDUINO UNO

                     The Arduino Uno is a versatile board that controls devices, reads sensor data, provides power
                     and enables interaction through input and output connections.

                                                                                                                      167
                                                                                         Designing Circuits with Tinkercad
