Study Notes
Arduino Basics
- Arduino 'shields' are expansion boards that can be plugged into an Arduino board to provide additional functionality.
- ATMEGA AVRs in an Arduino Uno act as the microcontroller, responsible for executing the code and controlling the board's components.
- The crystal resonator in an Arduino provides a precise clock signal to the microcontroller, ensuring it operates at the correct frequency.
Microcontrollers and Embedded Systems
- The main function of a microcontroller in embedded systems is to read inputs, process data, and control outputs according to a set of instructions.
Arduino Software Development Environment
- The Arduino software development environment provides a platform for writing, compiling, and uploading code to Arduino boards.
Arduino LLC
- Arduino LLC specializes in designing and producing microcontroller-based kits for building interactive electronic projects.
Arduino Code Functions
- The digital write function in Arduino code sets the voltage of a digital pin to either HIGH (5V) or LOW (0V).
- The delay(1000) function in Arduino code pauses the program for 1000 milliseconds (1 second).
- The digital read function in Arduino code reads the voltage of a digital pin and returns HIGH (5V) or LOW (0V).
- The void loop function in Arduino code is an infinite loop that runs continuously after the setup function.
- The analogWrite function in Arduino programming sets the voltage of an analog pin to a specific value between 0 and 5V.
- The map function in Arduino programming scales a value from one range to another.
- The delay function in Arduino programming pauses the program for a specified amount of time.
- The void setup function in Arduino code runs once at the beginning of the program, used to initialize variables and setup the board.
- The pinMode function in Arduino code sets the mode of a digital pin as either INPUT or OUTPUT.
- The analogRead function in Arduino programming reads the voltage of an analog pin and returns a value between 0 and 1023.
