                     The student will be able to:
                        Identify essential circuit components (resistors, capacitors, LEDs) and their roles.
                        Construct simple circuits on a breadboard and interpret basic circuit diagrams.
                        Explain what a microcontroller is and how the Arduino works.
                        Demonstrate the ability to use the Arduino IDE and Tinkercad to code and simulate projects.





                  Welcome to the first lesson of your robotics journey! In this lesson, we’ll revisit the essentials of
                  electronic circuits and microcontrollers before you dive deeper into building exciting projects. By
                  understanding the basics—how electricity moves, what role components like resistors and LEDs
                  play, and how a microcontroller like an Arduino can control them—you’ll set a strong foundation
                  for the hands-on robotics you’ll tackle in later lessons.




                            UNDERSTANDING CIRCUITS


                  UNDERSTANDING ELECTRICITY

                  Electricity is the flow of electrons through a conductor. The three fundamental electrical properties
                  are:

                     Voltage (V): The electrical potential difference between two points, measured in volts (V).
                     Current (I): The flow of electric charge, measured in amperes (A).

                     Resistance (R): The opposition to the flow of current, measured in ohms (Ω).


                  OHM’S LAW AND ITS APPLICATIONS
                  Ohm’s Law states that the relationship between voltage (V), current (I), and resistance (R) is

                  given by:
                  V = I × R
