# Run Your First Sketch
After setting up the IDE, we now upload a basic sketch to make sure everything is working properly.
### The Blink Example
This is the most basic example sketch from the board - blink the onboard **USR** LED. To run the example, follow the below steps:
1. Connect the board to your computer, as instructed in the previous chapter.
2. Select **LinkIt 7697** from the board: go to **Tools > Board**.
3. Select **Tools > Port:** menu, and then select **COM** ***XYZ***** (LinkIt 7697)**. The number ***XYZ*** can be different on each computer. The screenshot below is an example:
4.Now select the Blink example from **File > Examples > 01. Basics > Blink**, as shown below:
5.Click the **Upload** button on the toolbar, as shown below:
6.It may take some time to compile and upload the sketch. During the uploading process, the board's **TX** and **RX** LEDs will blink rapidly. Once the uploading completes, the IDE shows `Done uploading.` as shown below:
7.The board will automatically reboot, and the **USR** LED should start to blink once every second.
Note that unlike Arduino Uno, the **USR** LED maps to **P7** instead of P13 on the LinkIt 7697 board. Therefore the functional call:
```
digital_write(LED_BUILTIN, HIGH);
```
is equal to:
```
digital_write(7, HIGH); // 7 maps to P7 on LinkIt 7697 board
```
Refer to the [pinout diagram](https://labs.mediatek.com/en/download/1ega2lbl) to find other pin mapping definitions.
