Code Examples

### Example 1: Basic Solar-Powered Car Control using Arduino

This example demonstrates how to use the DIY 4 Wheel Drive Solar Powered Wooden Car Kit with an Arduino microcontroller to control the car's movement using the solar panel.

Hardware Requirements

Arduino Board (e.g., Arduino Uno)
 DIY 4 Wheel Drive Solar Powered Wooden Car Kit
 Jumper Wires

Software Requirements

Arduino IDE (version 1.8.x or later)

Code
```c
const int motorForward = 2;  // Pin for motor forward direction
const int motorBackward = 3;  // Pin for motor backward direction
const int solarPanelPin = A0;  // Pin for solar panel voltage measurement

void setup() {
  pinMode(motorForward, OUTPUT);
  pinMode(motorBackward, OUTPUT);
}

void loop() {
  int solarVoltage = analogRead(solarPanelPin);
  if (solarVoltage > 500) { // Adjust this value based on your solar panel's output
    digitalWrite(motorForward, HIGH);
  } else {
    digitalWrite(motorForward, LOW);
  }
  delay(100);
}
```
Explanation

In this example, we use the Arduino board to read the voltage from the solar panel and control the motor's direction based on the voltage level. When the solar panel's voltage is above a certain threshold (500 in this case), the motor is set to move forward. Otherwise, it stops.

### Example 2: IoT-Enabled Solar Car with Wi-Fi Connectivity using ESP32

This example demonstrates how to use the DIY 4 Wheel Drive Solar Powered Wooden Car Kit with an ESP32 microcontroller to create an IoT-enabled solar car that can be controlled and monitored remotely using Wi-Fi.

Hardware Requirements

ESP32 Board (e.g., ESP32 DevKitC)
 DIY 4 Wheel Drive Solar Powered Wooden Car Kit
 Wi-Fi Antenna (optional)
 Jumper Wires

Software Requirements

Arduino IDE (version 1.8.x or later) with ESP32 support
 Wi-Fi library for ESP32 (e.g., WiFi.h)

Code
```c
#include <WiFi.h>

const char ssid = "your_wifi_ssid";
const char password = "your_wifi_password";

WiFiServer server(80);

const int motorForward = 2;
const int motorBackward = 3;
const int solarPanelPin = A0;

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to Wi-Fi...");
  }
  Serial.println("Connected to Wi-Fi");
  server.begin();
}

void loop() {
  WiFiClient client = server.available();
  if (client) {
    String request = client.readStringUntil('
');
    if (request.indexOf("forward") != -1) {
      digitalWrite(motorForward, HIGH);
    } else if (request.indexOf("backward") != -1) {
      digitalWrite(motorBackward, HIGH);
    } else {
      digitalWrite(motorForward, LOW);
      digitalWrite(motorBackward, LOW);
    }
    client.stop();
  }
  int solarVoltage = analogRead(solarPanelPin);
  Serial.print("Solar Voltage: ");
  Serial.println(solarVoltage);
  delay(1000);
}
```
Explanation

In this example, we use the ESP32 board to connect to a Wi-Fi network and create a server that can be accessed remotely. The car's movement can be controlled by sending HTTP requests to the server using a web browser or a mobile app. The solar panel's voltage is also monitored and printed to the serial console.
