const int ledPin = 13; // LED connected to digital pin 13void setup() {
pinMode(ledPin, OUTPUT); // Set the LED pin as an output
}void loop() {
digitalWrite(ledPin, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(ledPin, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}
```Example 2: Reading Analog ValuesIn this example, we will use the Teensy 4.0 to read analog values from a potentiometer connected to analog pin A0.```c++
const int potPin = A0; // Potentiometer connected to analog pin A0void setup() {
Serial.begin(9600); // Initialize the serial interface
}void loop() {
int sensorValue = analogRead(potPin); // Read the analog value
Serial.print("Sensor value: ");
Serial.println(sensorValue); // Print the sensor value to the serial monitor
delay(100); // Wait for 100 milliseconds
}
```Example 3: Ethernet ConnectivityIn this example, we will use the Teensy 4.0 to connect to a network using Ethernet and send an HTTP request to a web server.```c++
#include <Ethernet.h>byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; // MAC address
byte ip[] = { 192, 168, 1, 100 }; // IP address
EthernetClient client; // Ethernet client objectvoid setup() {
Ethernet.begin(mac, ip); // Initialize the Ethernet interface
delay(1000); // Wait for 1 second
}void loop() {
if (client.connect("www.example.com", 80)) { // Connect to the web server
client.println("GET / HTTP/1.1");
client.println("Host: www.example.com");
client.println("Connection: close");
client.println();
client.stop(); // Stop the client
} else {
Serial.println("Failed to connect to the web server");
}
delay(10000); // Wait for 10 seconds
}
```Note: In this example, you need to replace the `mac` and `ip` arrays with your own MAC address and IP address, respectively.
