### Project 1 LED Blinking

**1.Introduction**

This project is one of the basic experiments, which can achieve LED blinking by graphical programming.

**2.Materials Required**

1. KEYESTUDIO UNO Control Board *1
2. V5 Sensor Shield*1
3. Piranha LED*1
4. Female to Female Dupont Line*1

**4.Sample Code**

```c
void setup()
{
  pinMode( 10 , OUTPUT);
}

void loop()
{
  digitalWrite( 10 , HIGH );
  delay( 1000 );
  digitalWrite( 10 , LOW );
  delay( 1000 );
}
```

**5.Result**

Then, you can see the high brightness LED blinking. We have now finished this project!

Note: Arduino software selection On the TOOLS menu, select UNO. COM port selects the same serial port with the first installation. You cannot download program unless both requirements are met.
