IoT:Bit - Internet WIFI Extension Board for Micro:Bit by ElecfreaksOverviewThe IoT:Bit is a WiFi extension board designed for the Micro:Bit, allowing users to connect their Micro:Bit projects to the internet and create IoT-based applications. This board provides a simple and convenient way to add WiFi capabilities to the Micro:Bit, making it ideal for a wide range of projects, from home automation to robotics.FeaturesCompatible with Micro:Bit
WiFi connectivity (2.4GHz, 802.11b/g/n)
Supports TCP/IP, UDP, HTTP, and FTP protocols
On-board antennas for improved signal strength
Micro-USB interface for programming and power
Supports both 3.3V and 5V power supplyCode Examples### Example 1: Connecting to WiFi Network and Sending HTTP RequestThis example demonstrates how to connect to a WiFi network using the IoT:Bit and send an HTTP request to a server.```python
import microbit
from IoTBit import IoTBit# Initialize IoT:Bit
iot = IoTBit()# Set WiFi credentials
iot.wifi_set_credentials("your_wifi_ssid", "your_wifi_password")# Connect to WiFi network
iot.wifi_connect()# Check if connection is successful
if iot.wifi_is_connected():
print("Connected to WiFi network")
# Send HTTP request
url = "http://example.com/iot_data"
data = "temperature=25&Celsius"
response = iot.http_post(url, data)
print("HTTP response: ", response)
else:
print("Failed to connect to WiFi network")
```### Example 2: Creating a Simple Web ServerThis example demonstrates how to create a simple web server using the IoT:Bit and serve a webpage.```python
import microbit
from IoTBit import IoTBit# Initialize IoT:Bit
iot = IoTBit()# Set WiFi credentials
iot.wifi_set_credentials("your_wifi_ssid", "your_wifi_password")# Connect to WiFi network
iot.wifi_connect()# Check if connection is successful
if iot.wifi_is_connected():
print("Connected to WiFi network")
# Create a simple web server
server = iot.http_server(80)
# Define a route for the root URL
@server.route("/")
def index():
html = "<h1>IoT:Bit Web Server</h1><p>Welcome to my IoT project!</p>"
return html
# Start the web server
server.start()
print("Web server started. Accessible at http://iotbit.local/")
else:
print("Failed to connect to WiFi network")
```### Example 3: Sending Data to MQTT BrokerThis example demonstrates how to connect to an MQTT broker using the IoT:Bit and send sensor data.```python
import microbit
from IoTBit import IoTBit
import random# Initialize IoT:Bit
iot = IoTBit()# Set WiFi credentials
iot.wifi_set_credentials("your_wifi_ssid", "your_wifi_password")# Connect to WiFi network
iot.wifi_connect()# Check if connection is successful
if iot.wifi_is_connected():
print("Connected to WiFi network")
# Set MQTT broker credentials
broker = "your_mqtt_broker"
port = 1883
topic = "iot_data"
# Connect to MQTT broker
client = iot.mqtt_connect(broker, port)
# Send sensor data to MQTT broker
while True:
temperature = random.randint(20, 30)
data = f"temperature={temperature}&Celsius"
iot.mqtt_publish(client, topic, data)
microbit.sleep(1000)
else:
print("Failed to connect to WiFi network")
```Note: These examples assume that you have the IoT:Bit library installed and configured correctly. You may need to modify the code to suit your specific project requirements.
