### Project 7 Reading-out Analog Value

**1.Introduction**

On a KEYESTUDIO UNO control board , there are 6 analog interfaces numbered from 0 to 5. Potentiometer is a typical output component of analog value. We will use it in this project. We simply use graphical programming read out analog value of analog 0 on serial monitor.

**2.Materials Required:**

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

**3.Connection Diagram:**

**4.Sample Code**

```c
void setup()
{
  Serial.begin(9600);
}

void loop()
{
  Serial.print("value:");
  Serial.print(analogRead(0));
  Serial.println();
  delay( 1000 );
}
```

**5.Result**

There are reading-out analog values as follow.
