Study Notes
Arduino Microcontroller
- A microcontroller is a vital component in modern electronics, acting as the heart and brain of electronic devices
- Its capabilities depend on the program instructions
- Arduino Uno is an open-source microcontroller board based on the ATmega328P microcontroller, developed by Arduino
- It is affordable, simple, cross-platform compatible, and has an active community
Arduino IDE
- It's an Integrated Development Environment (IDE) for writing and testing code
- The IDE provides a graphical user interface (GUI) for development
- It has a title bar showing the sketch filename
- The Menu bar offers access to all Arduino IDE commands
- Toolbar buttons include "Verify," "Open," "Save," and "Upload"
- The Serial Monitor connects the computer to the Arduino
- The Status Bar displays feedback on verification and compilation
Arduino Signals
- Signals transmit information between devices
- Analog signals are continuous waves changing over time
- Digital signals are discrete waves carrying information in binary form
Electronic Circuits
- Circuits are networks of electronic components connected by wires to allow the flow of electricity
- A direct current (DC) circuit flows in one constant direction
- An alternating current (AC) circuit periodically inverts its direction
Light Dependent Resistor (LDR)
- An LDR is a light-sensitive device used to measure light intensity
- It acts as a sensor and is small in size, requiring low power and no polarity.
- Applications include automatic lighting switches, camera shutter control, and light meters
Pulse Width Modulation (PWM)
- It's a technique used to simulate analog outputs by varying the pulse width of a digital signal
- PWM is used for tasks like controlling LED brightness, motor speed, and audio signals
- Duty cycle is the percentage of the time the signal is high, directly correlating with the brightness or power output
Piezo Buzzer
- A piezo buzzer is a small audio signaling device that creates sound when electricity causes its piezoelectric material to vibrate
- It operates with a wide voltage range and low current consumption
- Characteristics include wide operating voltage, lower current consumption, higher frequency output, robustness, and performance producing high volume levels with a wide frequency range
- Applications might involve input indicators, security systems, and automatic parking systems
- Limitations are that multiple piezo buzzers cannot be played simultaneously using the
tone()function, and a minimum frequency threshold is present
Ultrasonic Sensor (HC-SR04)
- An ultrasonic sensor measures distance using ultrasonic sound waves
- It can be programmed to detect proximity or measure ranging, and it has applications in vehicle parking, flood control, people detection, warehouse operation, and security.
DC Motor and Driver Shield
- DC motors convert direct current (DC) electrical energy into mechanical rotary energy
- The L293D Motor Driver Shield controls DC motors using the Arduino microcontroller
- This circuit board incorporates both a dual-channel H-Bridge motor driver and a 74HC595 shift register for extensive control over connected motors
