Wi-Fi and Bluetooth Configuration:
WiFi.h and BLEDevice.h can simplify this process.BOOT button while pressing the RESET button.Below is an example of how to use the ESP32-C3-Mini-1 to blink an LED connected to GPIO2:
// Example: Blink an LED connected to GPIO2 on the ESP32-C3-Mini-1
// Define the GPIO pin for the LED
#define LED_PIN 2
void setup() {
// Initialize the LED pin as an output
pinMode(LED_PIN, OUTPUT);
}
void loop() {
// Turn the LED on
digitalWrite(LED_PIN, HIGH);
delay(1000); // Wait for 1 second
// Turn the LED off
digitalWrite(LED_PIN, LOW);
delay(1000); // Wait for 1 second
