Practical C Programming

How to do it…

To take input from the serial port using Arduino, perform the following steps:

1. Invoke the Arduino IDE. Arduino opens up with a file showing its default content, as follows:

void setup() {// put your setup code here, to run once:}void loop() {// put your main code here, to run repeatedly:}

2. Connect the Arduino board to your PC.
3. From the Tools menu, select Port and confirm whether it shows COM3 (Arduino/Genuino Uno) or whatever Arduino board you have attached to your PC. Additionally, confirm whether the Board option from the Tools menu indicates the Arduino board that is attached to your PC. In my case, the Board option will show Arduino/Genuino Uno.
4. We will be attaching the LED to the output pin 13 of Arduino. Because the ...
