The following table outlines the key technical details of the DENEYAP Kart 1A:

The DENEYAP Kart 1A features a variety of pins for connecting sensors, actuators, and other peripherals. Below is the pin configuration:

1. Powering the Board:

   • Connect the board to a computer via a USB cable for programming and power.
   • Alternatively, use an external power supply (7-12V) connected to the VIN and GND pins.

2. Connecting Components:

   • Use the digital and analog pins to connect sensors, actuators, and other peripherals.
   • Ensure that the voltage and current requirements of connected components are within the board's specifications.

3. Programming the Board:

   • The board is compatible with the Arduino IDE. Install the ESP32 board package in the Arduino IDE to program the DENEYAP Kart 1A.
   • Select the appropriate board and port from the Arduino IDE settings.

4. Uploading Code:

   • Write your code in the Arduino IDE and upload it to the board via the USB connection.
   • Use the built-in serial monitor for debugging and monitoring data.

• Avoid exceeding the maximum voltage and current ratings of the pins to prevent damage.
• Use pull-up or pull-down resistors for stable digital input signals.
• Ensure proper grounding for all connected components to avoid noise and interference.
• When using Wi-Fi or Bluetooth, ensure the board is in a location with minimal signal interference.

The following example demonstrates how to read an analog sensor value and control an LED using the DENEYAP Kart 1A:

// Define pin connections
const int analogPin = A0; // Analog sensor connected to A0
const int ledPin = 13;    // LED connected to digital pin 13

void setup() {
  pinMode(ledPin, OUTPUT); // Set LED pin as output
  Serial.begin(9600);      // Initialize serial communication
}

void loop() {
  int sensorValue = analogRead(analogPin); // Read analog sensor value
  Serial.print("Sensor Value: ");          // Print sensor value to serial monitor
  Serial.println(sensorValue);

  // If sensor value exceeds threshold, turn on LED
  if (sensorValue > 500) {
    digitalWrite(ledPin, HIGH); // Turn on LED
  } else {
    digitalWrite(ledPin, LOW);  // Turn off LED
  }

  delay(500); // Wait for 500ms before next reading
}

1. Board Not Detected by Computer:

   • Ensure the USB cable is properly connected and functional.
   • Install the correct USB driver for the ESP32 chip.

2. Code Upload Fails:

   • Check that the correct board and port are selected in the Arduino IDE.
   • Press and hold the "BOOT" button on the board while uploading the code.

3. Wi-Fi or Bluetooth Not Working:

   • Verify that the correct libraries are included in your code.
   • Ensure the board is in a location with minimal signal interference.

4. Components Not Responding:

   • Double-check the wiring and connections.
   • Ensure the components are compatible with the board's voltage and current ratings.
