ARDUINO SERIAL HOW TO
ARDUINO SERIAL SERIAL

This feature, although it is not included within the loop(), is always listening, and when a serial event is captured by the Arduino board, as in our case, the sending from the PC to a numeric value, the serialEvent function is activated, and the code inside is executed. I left empty this function, but here you can implement everything you need to fulfill your specific needs.įinally, define a new function called serialEvent(). The function instead must contain all of the commands that will be executed from the board in a continuous cycle. But it can also be used as an input device that takes input. Finally, define a starting angle for the motor ( HOME position) which in my case I defined as 90°. The serial monitor is usually just used to display data from the Arduino on a computer monitor. Then you have to define the servo motor to be connected to pin 10 through the function attach() of the Servo library. The setup function practically takes care of initializing the board, and then, first of all activate a serial communication at 9600 baud. void setup()ĭefine now the two standard functions setup() and loop(). Finally, an index that will help you later to scan the array of characters. This array is used to store the values of the angles sent to the PC via serial port. Then you will define a strValues array of characters that will hold up to 4 characters (for example, ‘123,’). Define also the angle and newAngle variables that will hold the values of the angles.

Servo myservo įirst you define a myservo object, which corresponds to the servo motor. This library is specialized for controlling this type of motors when they are directly connected to the Arduino. (If you are interested, you can consult the official page here). This library provides us with a whole series of commands to manage Servo Motors in an easy and intuitive way. (Click here to go to the official page and download the latest release of the Arduino IDE).įirst, you have to include the Servo library already included within dell’Arduino IDE #include In Embedded Systems, Telecommunication, and Data Transmission applications, Serial Communication is known to be the process.
