In, we have selected pin 2 as the receive pin and pin 3 as the transmit pin. You can take advantage of some advanced C capabilities (streaming insertion syntax and templates) that you can use if you declare a streaming template in your sketch.Ĭonnect the device’s transmit line to the receive pin and the receive line to the transmit pin. You could combine them like this: Serial.print('At ') Serial.print(t) Serial.print(' seconds, speed= ') Serial.print(s) Serial.print(', distance= ') Serial.println(d) Or you could use the insertion-style capability of the compiler used by Arduino to format your print statements. For example, to print the following line: At 5 seconds: speed = 17, distance = 120 you’d typically have to code it like this: Serial.print('At ') Serial.print(t) Serial.print(' seconds: speed= ') Serial.print(s) Serial.print(', distance= ') Serial.println(d) That’s a lot of code lines for a single line of output. This can make complex print statements bulky. The sketch in this recipe uses a separate line of source code for each print statement. If your code expects byte variables to behave the same as char variables (that is, for them to print as ASCII), you will need to change this to Serial.write(val). Check the documentation to see how your display handles carriage returns, as some displays may not automatically advance to a new line after println statements. You can use a liquid crystal display as a serial output device, although it will be very limited in functionality. An easy-to-use freeware terminal program for Windows, Mac, and Linux An open source terminal program for Linux A free executable for the PC An open source virtual screen management program that supports serial communications included with Linux and Mac OS X Another open source terminal program for Linux An open source SSH program for Windows and Linux that supports serial communications An open source terminal program for the PC A shareware program for the Mac In addition, an article in the Arduino wiki explains how to configure Linux to communicate with Arduino using TTY (see ). Here are some that have been recommended by Arduino users. Displaying data in text or binary format (or both), displaying control characters, and logging to a file are just a few of the additional capabilities available from the many third-party terminal programs.
