Arduino uno User Manual

Using Different Serial Terminals
For trivial applications, the IDE’s serial monitor is sufficient, but you cannot
easily combine it with other applications, and it lacks some features. That
means you should have an alternative serial terminal to send data, and you
can find plenty of them for every operating system.
Serial Terminals for Windows
PuTTY
1
is an excellent choice for Windows users. It is free, and it comes as
an executable that doesn’t even have to be installed. The following figure
shows how to configure it for communication on a serial port.
After you have configured PuTTY, you can open a serial connection to the
Arduino. The following screenshot shows the corresponding dialog box. Click
Open, and you’ll see an empty terminal window.
