Nano Expansion Shield DocumentationThe Nano Expansion Shield is a versatile board designed to expand the capabilities of the Arduino Nano board. It provides additional digital and analog pins, as well as a built-in breadboard area, making it an ideal solution for prototyping and development projects.Features:Compatible with Arduino Nano boards
14 digital pins and 8 analog pins
Built-in breadboard area for easy prototyping
Onboard power LED and reset buttonCode Examples:### Example 1: Blinking an LED using digital pinsIn this example, we'll use the Nano Expansion Shield to connect an LED to digital pin 2 and make it blink.Hardware Requirements:Arduino Nano board

LED
220 resistor
Breadboard and jumper wiresCode:
```c
const int ledPin = 2; // Digital pin 2 on the Nano Expansion Shieldvoid setup() {
pinMode(ledPin, OUTPUT);
}void loop() {
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
}
```
Explanation:In this example, we define the digital pin 2 as an output pin using `pinMode()`. In the `loop()` function, we set the pin high using `digitalWrite()` to turn the LED on, wait for 1 second using `delay()`, and then set the pin low to turn the LED off.### Example 2: Reading analog values from a potentiometerIn this example, we'll use the Nano Expansion Shield to connect a potentiometer to an analog pin and read its value.Hardware Requirements:Arduino Nano board

Potentiometer
Breadboard and jumper wiresCode:
```c
const int potPin = A0; // Analog pin A0 on the Nano Expansion Shieldvoid setup() {
Serial.begin(9600);
}void loop() {
int potValue = analogRead(potPin);
Serial.print("Potentiometer value: ");
Serial.println(potValue);
delay(50);
}
```
Explanation:In this example, we define the analog pin A0 as the input pin for the potentiometer. In the `loop()` function, we use `analogRead()` to read the analog value from the potentiometer and store it in the `potValue` variable. We then print the value to the serial monitor using `Serial.println()`.### Example 3: Using the built-in breadboard area for an I2C sensorIn this example, we'll use the Nano Expansion Shield's built-in breadboard area to connect an I2C temperature sensor.Hardware Requirements:Arduino Nano board
Nano Expansion Shield
I2C temperature sensor (e.g., DS18B20)
Breadboard and jumper wiresCode:
```c
#include <Wire.h>const int tempSensorAddress = 0x48; // I2C address of the temperature sensorvoid setup() {
Wire.begin();
}void loop() {
Wire.beginTransmission(tempSensorAddress);
Wire.write(0x00); // Select temperature register
Wire.endTransmission();Wire.requestFrom(tempSensorAddress, 2);
int tempValue = Wire.read();
tempValue = (tempValue 9 / 5) + 32; // Convert Celsius to FahrenheitSerial.print("Temperature: ");
Serial.print(tempValue);
Serial.println("F");
delay(1000);
}
```
Explanation:In this example, we use the `Wire` library to communicate with the I2C temperature sensor. We define the I2C address of the sensor and use `Wire.beginTransmission()` to start the communication. We then write to the temperature register using `Wire.write()` and read the value using `Wire.requestFrom()` and `Wire.read()`. Finally, we convert the temperature value from Celsius to Fahrenheit and print it to the serial monitor.These examples demonstrate the versatility of the Nano Expansion Shield and its ability to expand the capabilities of the Arduino Nano board.
