I'm able to send data from my iOS app. return Statement Beendet eine Funktion und gibt einen Wert an die aufrufende Funktion zurück, wenn gewünscht GET data from arduino Asked 11 years, 1 month ago Modified 11 years, 1 month ago Viewed 754 times I created a simple Arduino program that receives a position value from a KnobControl Widget on my thingsboard dashboard and updates a servo position. Hi, anyone has encountered this while reading data from google sheet. I setup hardware part and initial software Dashboards in the Arduino Cloud are used to easily monitor & control your Arduino boards from a web interface. I have a String with 4 different data (temperature, humidity, pressure, luminous intensity). For example, the mobile app sends: 0x01 0x02 0x00 0x03 Reads the value of an analog pin in a 10-bit resolution (0-1023). Since return statement delivers only one value to the calling program, you can declare led1 and led2 as global variables and then assign their values in the called function. EEPROM is a memory whose values are kept when the board is powered off.
