Grove - Push Button

This project will use a Grove Push Button to toggle a Grove LED on.

---

1. Connect a Grove LED to a grove connector on your board and a Grove Push Button.
2. Begin a new Grove project using the Grove Project Import method at the bottom of this page.
3. In the Project Explorer on the left, under Sources, double click to open the file "arduinoApp.cpp".
4. Copy and paste the following code into this file to replace it's contents:

//--------- Push Button Test int ledPin = 6;    // LED connected to this digital pin number int inPin = 4;  // pushbutton connected to this digital pin number int val = 0;    // variable to store the read value void setup() {   pinMode(ledPin, OUTPUT);      // sets the digital pin 13 as output   pinMode(inPin, INPUT);      // sets the digital pin 7 as input } void loop() {   val = digitalRead(inPin);   // read the input pin   digitalWrite(ledPin, val);    // sets the LED to the button's value }

5. This code will turn on the LED whenever the Push Button is pressed and turn it off when it is released.
6. Select Project from the main menu and choose Build Project.
7. If there are any errors they will be displayed in the Problems tab.

Now follow the steps under Debugging your ARM Board Project.
