Study Notes
Lesson 2: Electronic Components and Their Uses
- Electronic Circuit: A closed loop allowing charge flow, including a load, power supply, and a switch.
- Current: The flow of electric charge in a circuit.
- Voltage: The measure of potential energy difference between two points, driving current flow.
- Resistance: The opposition to current flow, measured in ohms (Ω). Higher resistance limits current.
- Resistors: Electronic components limiting current, with resistance values. Higher values limit current more.
- Schematic Symbol: Shows resistors as having two terminals.
- Resistor Color Coding: A system of color bands on a resistor that represents its resistance value.
Lesson 3: The Basics of Arduino
- Arduino: An open-source electronic platform using programmable microcontrollers.
- Arduino IDE: Integrated Development Environment (software) for writing Arduino programs.
- Microcontroller: The main processing unit in Arduino, a single integrated circuit (MCU).
- Power Input: (Barrel Jack, USB Port) External power input, useful for connecting to a computer or independently.
- LEDs: Light Emitting Diodes used for visual feedback (e.g., indicating data transmission).
- Pins: Input/Output connections on the Arduino board used to interact with circuits.
- Digital Pins: Used for controlling other devices ON or OFF.
- Analog Pins: Used for measuring the flow of current.
- Reset Button: For restarting the Arduino board when needed.
Lesson 4: Using LED as a Light Source
- LED (Light Emitting Diode): Converts electrical energy into visible light.
- LED Structure: Includes an epoxy lens/case, wire bond, reflective cavity, semiconductor die, an anvil, post, leadframe, and flat spot.
- Arduino Function:
digitalWrite()sets the digital pin to HIGH (5V or 3.3V) or LOW (0V) to control LED state.
Lesson 5: LED as Decorative Lights
- LED Applications: Used in smartphones, TVs, and for creating decorative lighting displays.
- Energy Saving: Lower voltage consumption of LED lights compared to other options.
- Dimming: LED lights can be used for dimming and mood lighting.
Additional Information
delay()Function: Sets a pause in the Arduino program execution.delay(1000): Delays the program for one second.
