Applications:

                   Used to determine the required resistor value in LED circuits.
                   Helps in designing voltage dividers for sensors.

                   Ensures safe current flow in electronic components.


                 COMPONENTS OF A CIRCUIT
                 Before you dive into robotics, it’s important to understand basic electronic components that make

                 up circuits. Here are three fundamental components:


                 1. Resistors
                    Purpose: Resistors limit the flow of electric current, protecting components from
                    damage.

                   Unit of Measurement: Ohms (Ω)

                    Example Use: Resistors are used to control the brightness of an LED or limit
                    current flow in a circuit.

                 2. Capacitors

                 Purpose: Capacitors store and release electrical energy when needed.
                 Unit of Measurement: Farads (F)

                 Example Use: Capacitors are used in power supply circuits to smooth out voltage fluctuations.

                 3. Batteries
                 A battery is a device that stores and provides electrical energy to power circuits. It works by
                 converting chemical energy into electrical energy, supplying a steady flow of electrons to connected

                 components. Batteries come in different types and voltages, making them essential for powering
                 Arduino projects, sensors, and robotic systems.














                 Key Features of Batteries:
                   Voltage Rating: Determines the power output (e.g., 1.5V AA, 9V battery, 3.7V Li-ion).
