Lambda timer

You can modify the code as follows: void SquareWave(int pin, unsigned long offtime, unsigned long ontime, int Vpinled, float flow1, float flow2) { // to pass parameters to lambda function. You can use global vars static int _pin = pin; static int _Vpinled = Vpinled; static float _flow2 = flow2; analogWrite(pin, flow1); Blynk.virtualWrite(Vpinled, 0); timer.setTimeout(ontime, []…
