Arduino Uno CC3000 Wifi Shield DocumentationOverviewThe Arduino Uno CC3000 Wifi Shield is a popular Wi-Fi shield designed to work with the Arduino Uno board. It provides a simple and cost-effective way to add Wi-Fi connectivity to your Arduino projects. The shield is based on the CC3000 Wi-Fi module from Texas Instruments, which is a low-power, low-cost Wi-Fi solution.Hardware DescriptionThe Arduino Uno CC3000 Wifi Shield consists of the following components:CC3000 Wi-Fi module
Antenna
Reset button
LED indicators for Wi-Fi status and activity
SPI bus interface for communication with the Arduino boardSoftware LibraryTo use the Arduino Uno CC3000 Wifi Shield, you need to install the CC3000 library for Arduino. You can download the library from the Arduino website or install it through the Arduino Library Manager.Code Examples### Example 1: Connecting to a Wi-Fi NetworkIn this example, we will connect the Arduino Uno board to a Wi-Fi network using the CC3000 Wifi Shield.```c
#include <CC3000.h>#define WLAN_SSID "your_wifi_ssid"
#define WLAN_PASS "your_wifi_password"
#define WLAN_SECURITY WLAN_SEC_WPA2void setup() {
Serial.begin(9600);/ Initialize CC3000 module /
CC3000.begin();/ Connect to Wi-Fi network /
Serial.println("Connecting to Wi-Fi...");
if (!CC3000.connectToAP(WLAN_SSID, WLAN_PASS, WLAN_SECURITY)) {
Serial.println("Failed to connect to Wi-Fi");
while(1);
}
Serial.println("Connected to Wi-Fi!");
}void loop() {
/ Do something after connecting to Wi-Fi /
Serial.println("Connected to Wi-Fi!");
delay(1000);
}
```### Example 2: Sending an HTTP RequestIn this example, we will send an HTTP request to a web server using the CC3000 Wifi Shield.```c
#include <CC3000.h>
#include <CC3000Net.h>#define WLAN_SSID "your_wifi_ssid"
#define WLAN_PASS "your_wifi_password"
#define WLAN_SECURITY WLAN_SEC_WPA2#define SERVER_IP "google.com"
#define PORT 80CC3000Net net;void setup() {
Serial.begin(9600);/ Initialize CC3000 module /
CC3000.begin();/ Connect to Wi-Fi network /
Serial.println("Connecting to Wi-Fi...");
if (!CC3000.connectToAP(WLAN_SSID, WLAN_PASS, WLAN_SECURITY)) {
Serial.println("Failed to connect to Wi-Fi");
while(1);
}
Serial.println("Connected to Wi-Fi!");/ Initialize TCP client /
net = CC3000Net();
}void loop() {
/ Send an HTTP request to the server /
Serial.println("Sending HTTP request...");
net.connect(SERVER_IP, PORT);
net.print("GET / HTTP/1.1
Host: ");
net.print(SERVER_IP);
net.println("
");/ Read the response from the server /
while (net.connected()) {
if (net.available()) {
char c = net.read();
Serial.print(c);
}
}/ Close the connection /
net.close();
delay(1000);
}
```### Example 3: Scanner Application (List Available Wi-Fi Networks)In this example, we will create a scanner application that lists the available Wi-Fi networks in range.```c
#include <CC3000.h>void setup() {
Serial.begin(9600);/ Initialize CC3000 module /
CC3000.begin();
}void loop() {
int i;
int numNetworks = CC3000.scanNetworks();Serial.println("Available Wi-Fi networks:");
for (i = 0; i < numNetworks; i++) {
Serial.print(i + 1);
Serial.print(": ");
Serial.println(CC3000.SSID(i));
}delay(10000);
}
```TroubleshootingMake sure to install the CC3000 library for Arduino and import it in your sketch.
