Study Notes

Picoboard: A microcontroller-based development board used for prototyping and learning electronics.
Breadboard: A reusable platform for prototyping electronic circuits, allowing for easy connection and disconnection of components.

Jumper Wires: Used to connect components on a breadboard or other platforms, allowing for the flow of electrons between components.

LED (Light Emitting Diode): A semiconductor device that emits light when an electric current passes through it.
Resistor: A component that reduces the voltage or current in a circuit, protecting other components from excessive voltage.
Sensor: A device that detects and measures physical or environmental parameters, such as temperature, light, or motion.
Motor Driver: A component that controls the speed and direction of an electric motor.

Power Supply: A component that provides a stable voltage to a circuit, allowing for proper operation of electronic devices.

Buttons: Switches that allow users to interact with a circuit, providing input to control electronic devices.
Buzzers: Devices that produce a sound when an electric current passes through them, often used as an alert or notification.

Electron Flow: The movement of electrons from a negative terminal to a positive terminal, creating an electric current.
Voltage: The potential difference between two points in a circuit, measured in Volts (V).
** Typical Voltage Levels**: Common voltage levels in electronic circuits include 5V, 9V, 12V, and 24V.
Main Electricity: Household electricity is typically supplied at 120V or 230V AC (Alternating Current).
Frequency: The number of cycles or oscillations of an alternating current per second, measured in Hertz (Hz).
