Dimensions: 1.4 inches x 0.7 inches (35.56 mm x 17.78 mm)Code Examples### Example 1: Blinking an LED using Teensy 4.1This example demonstrates how to use the Teensy 4.1 to control an LED connected to digital pin 13.```c++
void setup() {
pinMode(13, OUTPUT); // Set pin 13 as an output
}void loop() {
digitalWrite(13, HIGH); // Turn the LED on
delay(500); // Wait for 500ms
digitalWrite(13, LOW); // Turn the LED off
delay(500); // Wait for 500ms
}
```### Example 2: Reading Analog Sensor Data using Teensy 4.1This example demonstrates how to use the Teensy 4.1 to read analog sensor data from pin A0.```c++
void setup() {
Serial.begin(9600); // Initialize serial communication at 9600bps
}void loop() {
int sensorValue = analogRead(A0); // Read analog value from pin A0
Serial.print("Sensor Value: ");
Serial.println(sensorValue); // Print the sensor value to the serial monitor
delay(100); // Wait for 100ms
}
```### Example 3: USB Serial Communication using Teensy 4.1This example demonstrates how to use the Teensy 4.1 as a USB serial device to communicate with a computer.```c++
void setup() {
Serial.begin(); // Initialize USB serial communication
}void loop() {
if (Serial.available()) { // Check if data is available from the computer
String incomingData = Serial.readStringUntil('
'); // Read data from the computer
Serial.print("Received: ");
Serial.println(incomingData); // Print the received data back to the computer
}
}
