Study Notes
Arduino Introduction
- Arduino is a programmable hardware platform, designed for artists, designers, tinkerers and makers.
- It is named after a pub in Italy.
- Arduino projects typically require minimal to no programming knowledge or electronics skills.
Arduino Hardware
- Arduino uses an Atmel AVR microcontroller, a small computer on a chip.
- The microcontroller runs at 16MHz with an 8-bit core.
- The AVR has 32 kilobytes of storage and 2 kilobytes of RAM.
- The Arduino board design combines a microcontroller with a USB-to-serial converter and additional components.
- Arduino boards can be powered from an external power supply via the barrel jack.
- The board uses a voltage regulator to control and stabilize power to the chip and other components.
- The board includes a crystal oscillator for accurate timekeeping. The crystal oscillator is rated at 16MHz.
- The Arduino board has a reset button and a dedicated RESET pin which can be used to restart the running code.
- The board has 3.3V and 5V output pins for powering external devices.
- The Arduino UNO has six analog input pins (A0-A5) which can read analog signals from sensors and convert them to digital values.
Arduino Programming
- The Arduino programming environment is based on the Processing development environment.
- It allows users to write, edit, compile, and upload Arduino code to the board.
- Arduino simplifies programming by providing a library of commands specific to the platform, making complex microcontroller functionalities easier to use.
- Arduino sketches can be written with C/C++ code, and the Arduino IDE can be extended with the avrlibc library.
- The Arduino bootloader allows for easy programming of the microcontroller through a serial connection, eliminating the need for external hardware.
- Arduino provides alternative programming environments to the IDE, such as Eclipse or NetBeans.
Hardware Errors
- Hardware errors can occur due to incorrect board connections, power issues, or incorrect settings.
- If the Serial port is not found or the board is not detected, check the USB connection and verify the correct serial port and board type are selected in the Tools menu.
