Basic Coding Examples

Alright, let's dive into some code! In this section, we'll explore some basic coding examples to get you familiar with programming the JVK1166Z ESP. These examples will cover fundamental concepts such as controlling GPIO pins, reading sensor data, and using the Wi-Fi and Bluetooth modules.

Blinking an LED

Let's start with the classic "Hello, World!" of embedded systems: blinking an LED. This simple example will demonstrate how to control a GPIO pin and toggle it on and off to blink an LED.

Connect an LED to GPIO pin 2 (or any other available GPIO pin) on your JVK1166Z ESP. Make sure to use a current-limiting resistor in series with the LED to prevent damage.
Open the Arduino IDE and create a new sketch.
Copy and paste the following code into the sketch:

const int ledPin = 2; // Define the LED pin

void 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
}

Verify the code by clicking the Verify button (the checkmark icon) in the Arduino IDE.
Upload the code to your JVK1166Z ESP by clicking the Upload button (the right arrow icon).

If everything is set up correctly, the LED should start blinking on and off every second. Congratulations, you've successfully controlled a GPIO pin and blinked an LED!

Reading Sensor Data

Next, let's explore how to read sensor data using the JVK1166Z ESP. This example will demonstrate how to read the value from an analog sensor, such as a temperature sensor or a light sensor.

Connect an analog sensor to an ADC pin (e.g., ADC0) on your JVK1166Z ESP.
Open the Arduino IDE and create a new sketch.
Copy and paste the following code into the sketch:

const int sensorPin = 36; // Define the sensor pin (ADC0)

void setup() {
  Serial.begin(115200); // Initialize serial communication
}

void loop() {
  int sensorValue = analogRead(sensorPin); // Read the sensor value
  Serial.print("Sensor Value: ");
  Serial.println(sensorValue); // Print the sensor value to the serial monitor
  delay(1000); // Wait for 1 second
}

Verify the code by clicking the Verify button in the Arduino IDE.
Upload the code to your JVK1166Z ESP by clicking the Upload button.
Open the Serial Monitor in the Arduino IDE (Tools > Serial Monitor).

You should see the sensor value printed to the Serial Monitor every second. The value will range from 0 to 4095, representing the analog voltage level on the sensor pin. You can then use this value to calculate the actual temperature, light level, or other physical quantity being measured by the sensor.

Connecting to Wi-Fi

Now, let's explore how to connect the JVK1166Z ESP to a Wi-Fi network. This example will demonstrate how to connect to a Wi-Fi network and print the IP address to the Serial Monitor.

Open the Arduino IDE and create a new sketch.
Copy and paste the following code into the sketch:

#include <WiFi.h>

const char* ssid = "YourWiFiSSID"; // Replace with your Wi-Fi SSID
const char* password = "YourWiFiPassword"; // Replace with your Wi-Fi password

void setup() {
  Serial.begin(115200); // Initialize serial communication
  WiFi.begin(ssid, password); // Connect to Wi-Fi

  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to Wi-Fi...");
  }

  Serial.println("Connected to Wi-Fi");
  Serial.print("IP Address: ");
  Serial.println(WiFi.localIP()); // Print the IP address
}

void loop() {
  // Do nothing
}
