Here is the code, I want to use, but it doesn't function. ledPin was used in the program before, which I found in the internet. I made small changes, e.g. the choice of the different servos. And I thought, that the modulo by using the pushbuttons would solve my problems, nothing... I need your help, please...
#include <Servo.h>
const int buttonPin = 2; // the pin that the pushbutton is attached to
const int ledPin = 13; // 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
Servo myservo9;
Servo myservo10;
Servo myservo11;
int potpin = 0;
int potpin2 = 2;
int potpin3 = 5;
int val = 0;
int val2 = 0;
int val3 = 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);
myservo9.attach(9);
myservo10.attach(10);
myservo11.attach(11);
}
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++;
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;
// 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 % 3 == 0) {
val = analogRead(potpin);
val = map(val, 3, 1023, 0, 176);
myservo9.write(val);
delay(25);
} //else {
//digitalWrite(myservo9, LOW);
//}
if (buttonPushCounter % 3 == 1) {
val2 = analogRead(potpin);
val2 = map(val2, 3, 1023, 0, 176);
myservo10.write(val2);
delay(25);
} // else {
// digitalWrite(myservo10, LOW);
// }
if (buttonPushCounter % 3 == 2) {
val3 = analogRead(potpin);
val3 = map(val3, 3, 1023, 0, 176);
myservo10.write(val3);
delay(25);
} //else {
//digitalWrite(myservo11, LOW);
// }
