How to use Arduino Board

Out of these 14 pins, some pins have specific functions as listed below, you can find the Pin Description in Arduino Uno

• Serial Pins 0 (Rx) and 1 (Tx): Rx and Tx pins are used to receive and transmit TTL serial data. They are connected with the corresponding ATmega328P USB to the TTL serial chip.
• External Interrupt Pins 2 and 3: These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.
• PWM Pins 3, 5, 6, 9, and 11: These pins provide an 8-bit PWM output by using the analog Write() function.
• SPI Pins 10 (SS), 11 (MOSI), 12 (MISO), and 13 (SCK): These pins are used for SPI communication.
• In-built LED Pin 13: This pin is connected with a built-in LED, and pin 13 is HIGH–the LED is on and pin 13 is LOW, it’s off.
• Analog pin 4 (SDA) and pin 5 (SCA) are used for TWI communication using the Wire library.

Arduino Communication 

A computer, an additional Arduino board, and other microcontrollers can all connect with Arduino. The ATmega328P microcontroller provides UART TTL (5V) serial communication which can do using digital pin 0 (Rx) and digital pin 1 (Tx). An ATmega16U2 on the board channels this serial communication over USB and appears as a virtual COM port to software on the computer. The ATmega16U2 firmware uses the standard USB COM drivers, and no external driver is needed. on Windows, a .inf file is required.

The Arduino software

The Arduino software includes a serial monitor that allows simple textual data to send to and from the Arduino board. There are two RX and TX LEDs on the Arduino board which will flash after data is being transmitted via the USB-to-serial chip and USB connection to the computer (not for serial communication on pins 0 and 1). A Software Serial library allows for serial communication on any of Uno’s digital pins. The ATmega328P supports I2C (TWI) and SPI communication. The Arduino software includes a Wire library to simplify the use of the I2C bus. Buy Arduino uno Sri Lanka to make your work easy.

Other Development Boards

Where to use ARDUINO DUE

Although ARDUINO boards are usually popular, DUE is least popular because of controller being ARM and I/O pins +3.3v OUTPUTS are not compatible with most sensors. Though it is least popular it is most recommended when designing complex systems like CNC or 3D printer. Also the ARDUINO DUE is an open source platform where one can get all related data and original module schematics. So you can customize the system depending on the need.

There are few cases where DUE is chosen over others:

Case1: Where the system processing is huge. UNO or NANO are boards all have a maximum clock speed of 16 MHz, so they can perform functions limited to their capabilities. They cannot process high end programs for applications like 3D printer. With 84MHz clock speed more than five times speed of UNO, DUE could do process more data than UNO or NANO.

Case2: Where you need to connect more peripherals. DUE has over 54 I/O pins. So when there are many peripherals in an application using DUE is ideal.

Case3: Where application needs to provide analog output. UNO and NANO cannot provide analog output which is need in some applications. In those cases DUE will solve the problem.

Case4: With many PWM and ADC outputs, DUE can run application program which cannot be solved by other ARDUINO.

Case5: With CAN interface DUE can be used on systems with high Electromagnetic Interference where other communications may fail. This facility is not present on other ARDUINO BOARDS.

How to use ARDUINO DUE

DUE is used similar to any other development board. All that needs to be done is programming the controller and provide the appropriate peripheral to get system running. We will discuss the programming of DUE in step by step below.

1. DUE can be programmed by connecting both USB ports to PC. Although there are two, PROGRAMMING PORT is preferred over NATIVE USB port in order to avoid controller crashing during programming. So connect DUE to PC using PROGRAMMING port is ideal.
2. Download and install ARDUINO IDE software. [ https://www.arduino.cc/en/Main/Software ]
3. Next get the link between PC and DUE. Run a test program to blink LED provided on board.
4. List the functions to be performed by DUE.
5. Write the functions as program in IDE.
6. Remember for ARDUINO IDE the program is written in ‘C’ language.
7. After completing the writing. Burn the program to DUE through IDE.
8. Disconnect the programmer. Provide the power and attach the necessary peripherals. After resetting the controller, it executes the program and provides the desired output.

Applications

1. Hobby projects.
2. Power supply systems.
3. IoT applications.
4. Display systems.
5. Instrumentation.
