Study Notes
Overview of Arduino
- Arduino is an open-source prototype platform that combines hardware and software for easy access to micro-controller programming.
- It consists of a programmable circuit board (microcontroller) and Arduino IDE, a software for writing and uploading code.
Features of Arduino
- Capable of reading both analog and digital signals from various sensors; effects include motor activation and LED control.
- Programming does not require a separate programmer; code is uploaded via USB cable.
- Arduino IDE employs a simplified version of C++, making it accessible for beginners.
- Standardized form factor facilitates the breakdown of micro-controller functions into understandable components.
Board Types
- Various Arduino boards exist, differing in microcontroller type, number of inputs/outputs, speed, and operating voltage.
- Some boards support 3.7V battery operation, while others require at least 5V for functionality.
Analog Input Pins
- The Arduino UNO has five analog pins (A0 to A5) for receiving signals from analog sensors like humidity or temperature sensors.
Main Microcontroller
- Each Arduino board features a distinct microcontroller, primarily sourced from ATMEL, which acts as the board's central processing unit.
- Microcontroller identification is critical before uploading programs; data sheets provide detailed information.
ICSP Pin
- The ICSP (In-Circuit Serial Programming) pin enables programming of the Arduino via an SPI (Serial Peripheral Interface) setup.
LED Indicators
- A power LED indicates proper board connection when lit.
- TX (transmit) and RX (receive) LEDs signal serial communication activity, with TX flashing at variable speeds based on the baud rate.
Digital I/O Configuration
- Arduino UNO features 14 digital I/O pins; 6 of these support PWM (Pulse Width Modulation) output.
- The power source for the board can be adjusted via a jumper located between the USB and power connectors.
Getting Started with Arduino IDE
- Launch Arduino IDE after downloading and unzipping the application.
- Users can create a new project or open an existing project example, such as the "Blink" example, which toggles an LED on and off.
Selecting Your Board
- To upload a program without errors, ensure the correct board is selected in the IDE under Tools -> Board, matching the board connected to the computer.
