inthttpCode=https.GET(); If the response code is a positive number, it means the connection was established successfully, so we can read the response payload using thegetString()method on thehttpsobject. Then, we can print the payload in the Serial Monitor. In a practical application, you...
Lassen Sie uns einen String definieren und einige seiner Zeichen durch andere ersetzen. Code: String ch1 = "hello world"; void setup() { Serial.begin(9600); for (int i = 1; i < 5; i++) { ch1[i] = '.'; } Serial.println(ch1); } void loop() {} Ausgabe: h... world ...
