All the pins of micro controller IC are connected to the board which makes it easier for us to access the GPIO pins and program the IC.

Reading data from an Arduino's USB/serial port using Debian Linux Here is a later approach using Minicom, from a reader. Thanks Martin, I've learned something new The Arduino UNO has its own FTDI chip whose function is to convert TTL signal levels to USB. This is why you can communicate with the board serially using a USB cable and the Serial Monitor feature of the Arduino IDE

Just about everyone who is involved with serial communication will have his/her RS232 to USB converter. Today's PCs don't even bother to support RS232. Consequently, a USB converter is mandatory to monitor RS232 data traffic. All this appears to render the following project obsolete. However, when it comes to a protocol converter, i.e. the conversion of data frames, this solution might come in. Arduino MEGA 2560 and Due. Both the MEGA 2560 and Due have 4 serial ports in total. One that connects through a USB port chip to the USB device port on the board and three extra serial ports that connect to pins on one of the pin headers of the board Arduino Zero (Arduino.cc) Arduino M0 has two serial ports, M0 pro and Zero have three. Images: This is the Arduino Zero, same form as M0 pro. About Serial ports, I have to say that Arduino M0 only has the native USB port and the Serial pins 0 and 1. Differences between Serial ports: Serial port of pins 0 and 1

Data Terminal Ready (DTR) is simply a control signal in RS232 serial communication, transmitted from data terminal equipment (DTE), like a PC, to data communications equipment (DCE), for example a modem, which will be used to indicate that the terminal is ready for communications and the modem can now initiate a communication channel. Stack Exchange Network Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. That is how we upload a code to an Arduino board especially Arduino Pro Mini with no USB port using a USB to Serial RS232 PL2303 TTL Adapter with or without a DTR pin. Bluetooth is the most popular way of connecting an Arduino to a smartphone wirelessly. In this tutorial, we will create an arduino-bluetooth interface and send messages from an arduino to smartphone and arduino to a personal computer. Bluetooth is a radio communication protocol that was created as a wireless alternative to the RS-232 serial. The CH340 chip is used by a number of Arduino compatible boards to provide USB connectivity, you may need to install a driver, don't panic, it's easier than falling off a log, and much less painful. In the Arduino IDE when the CH340 is connected you will see a COM Port in the Tools > Serial Port menu, the COM number for your device may vary. This was introduced in Arduino IDE 1.0.1. Returns true if the specified serial port is available. This will only return false if querying the Leonardo's USB CDC serial connection before it is ready. Data type: bool. void setup () { //Initialize serial and wait for port to open: Serial.begin (9600); while (!Serial) { ; // wait for serial.
