#6490136
Ja, ich habe es einfach per Drag and Drop kopiert.
Ich gebe es zu ;-(
Ich versuche aber mit Mühe den Fehler zu finden.
Kann jemand helfen???
Es ist möglich das ich mit dem Boardverwalter nicht die richtige, mir
vorliegende Hardware getroffen habe.
Kann es schon daran liegen?
#include "BluetoothSerial.h" //Header File for Serial Bluetooth, will be
added by default into Arduino
BluetoothSerial ESP_BT; //Object for Bluetooth
int incoming;
int LED_BUILTIN = 2;
void setup() {
Serial.begin(9600); //Start Serial monitor in 9600
ESP_BT.begin("ESP32_LED_Control"); //Name of your Bluetooth Signal
Serial.println("Bluetooth Device is Ready to Pair");
pinMode (LED_BUILTIN, OUTPUT);//Specify that LED pin is output
}
void loop() {
if (ESP_BT.available()) //Check if we receive anything from Bluetooth
{
incoming = ESP_BT.read(); //Read what we recevive
Serial.print("Received:"); Serial.println(incoming);
if (incoming == 49)
{
digitalWrite(LED_BUILTIN, HIGH);
ESP_BT.println("LED turned ON");
}
if (incoming == 48)
{
digitalWrite(LED_BUILTIN, LOW);
ESP_BT.println("LED turned OFF");
}
}
delay(20);
}
