Example Code for Arduino UNO

While the USB-6002 is typically used with a computer, you can interface it with an Arduino UNO for certain applications. Below is an example code to read an analog input from the USB-6002 and display it on the Arduino Serial Monitor.

// Example code to read analog input from USB-6002 and display on Serial Monitor

void setup() {
  Serial.begin(9600); // Initialize serial communication at 9600 baud rate
}

void loop() {
  int sensorValue = analogRead(A0); // Read analog input from pin A0
  float voltage = sensorValue * (5.0 / 1023.0); // Convert to voltage
  Serial.print("Analog Input: ");
  Serial.print(sensorValue);
  Serial.print(" Voltage: ");
  Serial.println(voltage);
  delay(1000); // Wait for 1 second before next reading
}

Note: This example assumes that the analog input from the USB-6002 is connected to the Arduino's analog pin A0. Adjust the pin number and voltage conversion factor as needed for your specific setup.

By following this documentation, users can effectively utilize the USB-6002 for their data acquisition and control applications, ensuring accurate and reliable performance.
