Olá ! Abraço a todos. Agradeço aos Amigos pela atenção e ajuda.
Consegui resolver o problema do botão para acionar o servo, utilizando esse sketch com pequena modificação.
// this constant won't change:
const int buttonPin = 2; // the pin that the pushbutton is attached to
const int ledPin = 8; // the pin that the LED is attached to
// Variables will change:
int buttonPushCounter = 0; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 0; // previous state of the button
unsigned long intervalo = 0;
void setup() {
// initialize the button pin as a input:
pinMode(buttonPin, INPUT);
// initialize the LED as an output:
pinMode(ledPin, OUTPUT);
// initialize serial communication:
Serial.begin(9600);
}
void loop() {
// read the pushbutton input pin:
buttonState = digitalRead(buttonPin);
// compare the buttonState to its previous state
if (buttonState != lastButtonState) {
// if the state has changed, increment the counter
if (buttonState == HIGH){
// if the current state is HIGH then the button
// wend from off to on:
buttonPushCounter++;
intervalo = millis();
Serial.println("on");
Serial.print("number of button pushes: ");
Serial.println(buttonPushCounter);
} else {
// if the current state is LOW then the button
// wend from on to off:
Serial.println("off");
}
// Delay a little bit to avoid bouncing
delay(50);
}
// save the current state as the last state,
//for next time through the loop
lastButtonState = buttonState;
// se passar mais que 2 segundos entre os pressionar de botões, ele volta a zero e precisa pressionar duas vezes de novo
if(millis() > intervalo+2000){
buttonPushCounter = 0;
}
// turns on the LED every four button pushes by
// checking the modulo of the button push counter.
// the modulo function gives you the remainder of
// the division of two numbers:
if (buttonPushCounter == 5) {
digitalWrite(ledPin, HIGH);
delay(2000);
digitalWrite(ledPin, LOW);
buttonPushCounter = 0;
}
//else {
//digitalWrite(ledPin, HIGH);
//}
}
