Question

In C++ (compatable with arduino) write a program that will debounce and interrupt (the interrupt used is a push button) so that when you click the button once a servo motor turns to 0 degrees and when you press it twice consecutively within a 1 second interval the service motor turns 45 degrees. When pressed three times consecutively within that same one second interval it turns the servo motor 90 degrees. Pressed 4 times consecutively and the servo motor turns 180 degrees.

Answer 1

For any doubts comment below.

#include <Servo.h>
  
int i = 0;
int btn=0;
int c1=0;
int laststate=0;
int currstate =0;
Servo myservo;
void setup() {
myservo.attach(9);
pinMode(13,OUTPUT);
pinMode(6,INPUT);
Serial.begin(9600);
}

void loop() { c1=0;
if(laststate==currstate){

for(i=0;i<1000;i++){
btn = digitalRead(6);
if(btn>=1)
{ delay(100);
btn = digitalRead(6);

if(btn==0)
{
c1+=1;
}
}
delay(1);
}
}

if(c1==0)
{
currstate=laststate;
}
else if(c1==1)
{
myservo.write(0);
Serial.println("0");
laststate=1;
}
else if(c1==2)
{
myservo.write(45);
Serial.println("45");
laststate=2;
}
else if(c1==3)
{
myservo.write(90);
Serial.println("90");
laststate=3;
}
else if(c1==4)
{
myservo.write(180);
Serial.println("180");
laststate=4;
}

}
