Getting Started with ESP32

Getting Started with ESP32

What is ESP32?

The ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and Bluetooth.

What You’ll Need

• ESP32 development board
• USB cable
• Arduino IDE or VS Code with PlatformIO
• Required drivers (CP210x or CH340)

Installation Steps

1. Install Arduino IDE or VS Code with PlatformIO
2. Add ESP32 board support
3. Install necessary USB drivers
4. Connect your ESP32 board
5. Select the correct board and port

Your First Program: WiFi Scan

#include "WiFi.h"

void setup() {
  Serial.begin(115200);
  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  delay(100);
}

void loop() {
  Serial.println("Scan start");
  int n = WiFi.scanNetworks();
  Serial.println("Scan complete");

  for (int i = 0; i < n; ++i) {
    Serial.print(i + 1);
    Serial.print(": ");
    Serial.print(WiFi.SSID(i));
    Serial.print(" (");
    Serial.print(WiFi.RSSI(i));
    Serial.println(")");
    delay(10);
  }
  Serial.println("");
  delay(5000);
}
