# Grove Base Shield for Photon
**Grove Base Shield for Photon** is an expansion shield board which incorporate [Grove](https://app.gitbook.com/Grove_System) port on which you can build more powerful and intelligent applications with much richer and cost-effective Grove functional modules. It gets three digital ports, two analog ports, two I2C ports and one UART port. It a kind of plug-and-play board which will accelerate your prototyping process dramatically.

## Getting Started
**Note:** In this case we show you a general development environmental.
### Material required
* [Particle Photon](http://www.seeedstudio.com/depot/Particle-Photon-p-2527.html) × 1
* USB cable (type A to micro type-B) × 1
* A PC or Mac
* Grove Base Shield for Photon × 1
* [Grove - Buzzer](http://www.seeedstudio.com/depot/Grove-Buzzer-p-768.html?cPath=38) × 1
### Buzzing
1\. Refer to \[here]\() to connect to a device (PC or Mac).
!!!Note 1. We recommend that you choose **node.js v4.2.3 LTS** especially for Windows 10 user. 2. You may need to one more steps after run command **particle setup**, that is, connect you device (PC or Mac) to a wi-fi AP whose name contain **Photon**, especially on Windows 10.
2\. Use \[Web IDE]\() for your project. Login with your account and choose your device (click the 2nd last icon on left column).
!!!Note We recommend you choose [Web IDE](https://build.particle.io/) to compile or flashing your code to Photon which is much quicker than using Particle Dev, if your internet connectivity is not so good.
3\. Connect them like following:
4\. Now you can copy following code to Web IDE and flash them to Photo by clicking a lighting-like icon (the 1st icon on left column).
!!!Note Copy the code only to the tab named ***filename.ino***.
```

Buzzing
Use digital pin D4

int led1 = D4; //set D4 as output
void setup() {
pinMode(led1, OUTPUT);
}
void loop() {
// enable buzzing
digitalWrite(led1, HIGH);
// We'll leave it on for 1 second...
delay(1000);
// Then we'll turn it off...
digitalWrite(led1, LOW);
// Wait 1 second...
delay(1000);
// And it will repeat!
}
