My purpose is to use Arduino to set up communication between a PC and an Android device using an HC-05 bluetooth module. I use the USB communication between the PC and the Arduino (Serial Monitor) and a SoftwareSerial to connect to the HC-05.

What is the meaning of ' interfacing' here? Interfacing is such as ‘communication’ between two devices (or more) that works in a digital world (only know the logic '1' and '0') with a controlled object which is usually in analog quantities such as actuators and sensors. Simple example is when you want to move a robotic arm with a computer. Here, the computer acts as a control center and a robot arm as the object of control. How to become a computer with only working on digital logic '1' and '0' to control a robotic arm? That is called 'interfacing' J.

The second: data exchange. For the data, it could have any kind of data but in binary logical level. I’ll explain it as you go along. The third: port as data entrance. Well, they are most important because as I described in the first paragraph, it’s rarely computer equipped with parallel or serial port for data exchange.

One solution is using a converter, either usb to parallel (obsolete too) or usb to serial. One of them is using a microcontroller to act as 'slave' that translates command from computer simultaneously. Another is using V-USB technique by issuing data to a USB port via libUsb driver. This method requires a microcontroller burned V-USB firmware. The difference, first technique actually using USB data frames sent to the external device, unlike the second option that converts into a classic serial protocol into USB payload. Okay, for easier we will choose second method and using Arduino as serial-ready board.

For experiment, prepare an Arduino Uno, USB cable (type-B) and a PC / laptop. For example, we will try to turned on/off internal LED that exist in Arduino Uno board (pin numbers 13) controlled by a executable application in laptop (written in Delphi). This program is intended as a simple representation of 'interfacing' in digital to analog world.

Then, you could develop it for more complex applications, such as connects Arduino to other actuators (ex: motor driver for moving a robot arm). Here are all steps to on/off internal LED Arduino board on pin 13.

Fast break pro basketball serial numbers. We have learnt quite a bit in the past 8 chapters. In this ninth chapter we will start we will combine some of the things we’ve talked about and with that show you how we can read something from the Serial Monitor of the Arduino IDE, so a user can enter text or numbers. This is the ninth part of a series of articles I’ve written to get beginners started with Arduino Programming in the programming language C, which I’ve written with the intend to teach my 13 year old nephew (Bram) to get started with the Arduino. After all, he wants to build a robot, but without some basic knowledge about programming, he won’t get far. Besides an introduction into the language C, the default language used for Arduino Programming, “Arduino Programming for Beginners” will also touch topics like how to setup an Arduino, get a developers environment running, and look at a few basic electronic parts which we connect to our Arduino. Overview of this Chapter • 1 • 2 • 3 • • • 4 • 5 • • 6 A complete overview of this course can be found here:. Input though the Serial Monitor Now we have done quite a lot with the Serial Monitor – just so we can see the results of our programs.
