Param Asint

Param Asint. int pinValue = param asInt () digitalWrite (LED pinValue)} // This function sends Arduino&#39s up time every second to Virtual Pin (1) // In the app Widget&#39s reading frequency should be set to PUSH This means // that you define how often to send data to Blynk App void myTimerEvent {// You can send any value at any time.

int virtual_pin_value = param asInt () Copied! This tells the code to get the value parameter from the virtual pin and store it in the local integer variable called virtual_pin_value We can then use this value to do different actions if the button wid.

BlynkvirtualWrite(5 some_value) } This function will be called every time App Widget writes value to Virtual Pin 1 * BLYNK_WRITE(1) { BLYNK_LOG(“Got a value %s” paramasStr()) // You can also use paramasInt() and paramasDouble() } BLYNK_READ/BLYNK_WRITE functions are effectively “getters/setters” of the Virtual Pins if you&#39re familiar with this concept in other programming languages.

The Blynk nomenclature is kind of confusing When you want to remotely monitor the state of a widget on your phone (like a button) with your Arduino sketch you use the callback function BLYNK_WRITE (vPIN) int value BLYNK_WRITE (V7) { value = paramasInt () // Get value as integer } This callback gets called every time the widget changes state.
