Arduino code language tutorial9/4/2023 ![]() ![]() Type the following in your Arduino sketch, below the code we already wrote: language:cpp ![]() For our first example, we'll just send the string 'Hello, world!' over the serial port, over and over (and over). ![]() This is bad.Īfter our setup() method, we need a method called loop(), which is going to repeat over and over as long as our program is running. For now, all you need to now about baud rate is that (basically) it's the rate at which we're sending data to the computer, and if we're sending and receiving data at different rates, everything goes all gobbledy-gook and one side can't understand the other. Here, we're using it to start serial communication from the Arduino to our computer at a baud rate of 9600. initialize serial communications at a 9600 baud rate Click in the white area and type the following (or copy and paste if you feel lazy): language:cpp The nice big white space is where we are going to write our code.
