Arduino Nano 33 BLE with HeadersOverviewThe Arduino Nano 33 BLE with Headers is a small, powerful board that combines the benefits of the Arduino Nano form factor with the latest Bluetooth Low Energy (BLE) technology. It is based on the nRF52840 microcontroller, which provides a high level of processing power and a range of peripherals, including BLE, USB, and more. This board is ideal for IoT projects, wearable devices, and other applications where size and low power consumption are critical.Key FeaturesnRF52840 microcontroller
Bluetooth Low Energy (BLE) 5.0
USB interface
25 digital I/O pins
8 analog I/O pins
16-bit ADC
Operating voltage: 1.7V to 3.6V
dimensions: 45mm x 18mmCode Examples### Example 1: Basic BLE Connection and Data TransmissionIn this example, we will demonstrate how to use the Arduino Nano 33 BLE with Headers to connect to a BLE peripheral device and transmit data.```c++
#include <ArduinoBLE.h>void setup() {
Serial.begin(9600);// Initialize BLE
if (!BLE.begin()) {
Serial.println("Failed to initialize BLE");
while (1);
}// Set BLE device name
BLE.setLocalName("ArduinoNano33BLE");// Start BLE advertising
BLE.advertise();
Serial.println("BLE advertising started");
}void loop() {
// Poll for BLE events
BLE.poll();// Check if a central device is connected
if (BLE.connected()) {
// Send data to the central device
String data = "Hello, world!";
BLE.write(data);
delay(100);
}
}
```### Example 2: Reading Data from an Analog Sensor using ADCIn this example, we will demonstrate how to use the Arduino Nano 33 BLE with Headers to read data from an analog sensor using the built-in Analog-to-Digital Converter (ADC).```c++
const int sensorPin = A0; // Select the analog input pinvoid setup() {
Serial.begin(9600);
}void loop() {
// Read the analog value from the sensor
int sensorValue = analogRead(sensorPin);// Print the sensor value
Serial.print("Sensor value: ");
Serial.println(sensorValue);// Wait for 100ms before taking the next reading
delay(100);
}
```Note: In this example, we assume that the analog sensor is connected to the A0 pin of the Arduino Nano 33 BLE with Headers.Additional Resources[Arduino Nano 33 BLE with Headers datasheet](https://docs.arduino.cc/static/5358a7f5a1413f31f7da51d8/nano-33-ble- datasheet.pdf)
