#Hooking up a servo motor arduino serial#

Inside the setup() function we will first open the serial communication at a baud rate of 9600.

Next we will declare three int varaibles to hold the x value, y value and the push button state. We will first define the analog and digital pins that we have connected with the VRx, VRy, and SW pins of the Joystick module. Serial.println (button_State) // Printing the button is high or low on the displayĭelay (1000) // This will add delay between readings Serial.print (' | Button State is ') // Printing “ Button state ” on the display Serial.print (y_Position) // Printing value of y key on the display Serial.print (' | Value of Y key is ') // Printing “ Value of Y key is ” on the screen Serial.print (Horizontal_Position) // Printing value of x key on the display Serial.print (' Value of X key is ') // Printing “ Value of X key is ” on the display Y_Position = analogRead (y_key) // Reading the value from A1 and storing in y_Positionīutton_State = digitalRead (Push_Button) // Reading the digital pin 2 is high or low Horizontal_Position = analogRead (x_key) // Reading the value from A0 and storing in Horizontal_Position If you have Arduino version previous to Arduino 1.0.1, then use these commands for activating pull-up resistor. PinMode (Push_Button, INPUT_PULLUP ) // This will activate pull-up resistor on the push-button pin PinMode ( y_key, INPUT ) // Selecting Arduino analog A1 pin as input PinMode ( x_key, INPUT ) // Selecting Arduino analog A0 pin as input Serial.begin (9600) // initializing serial communications at 9600 bps: Int button_State = 0 // Declaring a variable for storing the value Int y_Position = 0 // Declaring a variable for storing the value Int Horizontal_Position = 0 // Declaring a variable for storing the value Int Push_Button = 2 // initializing digital pin 2 for joystick’s press to select button Int y_key = A1 // initializing A1 for storing the joystick’s y key value int x_key = A0 // initializing A0 for storing the joystick’s x key value Moreover, the switch output will be shown as well. This sketch will display on the serial monitor, the Joystick physical positions in terms of x and y coordinates. Open your Arduino IDE and go to File > New to open a new file.
