Connecting your Arduino

In the previous chapter, we learned how to connect an Arduino to our system. Let's do it again.

We will discuss few of them in Chapter 10, Few Error Handlings. If you have the latest version of Arduino IDE and go to Tools | Port , and you will see a bunch of port lists, but on the port on which your Arduino is connected, you will see something similar to the following. In my case, it is port number COM13 (on Windows). Select the...
