Could anyone help me I need to make a system that rotates a servo motor after a counter hits 9 i've made the counter, it just uses a button that can make it go up one number and I just need help making the servo motor rotate after a timer hit's 9, or I could do this by making the arm rotate after 9 button presses could someone tell me how to do this?
Heres the video I used to make the counter: Arduino 7-Segment counter 0-9 with push button up and down - YouTube
Also heres the code for the counter:
const int a = 8; //For displaying segment "a"
const int b = 9; //For displaying segment "b"
const int c = 4; //For displaying segment "c"
const int d = 5; //For displaying segment "d"
const int e = 6; //For displaying segment "e"
const int f = 2; //For displaying segment "f"
const int g = 3; //For displaying segment "g"
bool bPress = false;
const int IncbuttonPin = 10;
const int DecbuttonPin = 11;
// Variables will change:
int buttonPushCounter = 0; // counter for the number of button presses
int IncbuttonState = 0; // current state of the button
int lastIncbuttonState = 0; // previous state of the button
int DecbuttonState = 0; // current state of the button
int lastDecbuttonState = 0; // previous state of the button
void setup() {
// put your setup code here, to run once:
pinMode(a, OUTPUT); //A
pinMode(b, OUTPUT); //B
pinMode(c, OUTPUT); //C
pinMode(d, OUTPUT); //D
pinMode(e, OUTPUT); //E
pinMode(f, OUTPUT); //F
pinMode(g, OUTPUT); //G
pinMode( IncbuttonPin , INPUT_PULLUP );
pinMode( DecbuttonPin , INPUT_PULLUP );
Serial.begin(9600);
displayDigit(buttonPushCounter);
}
void loop() {
IncbuttonState = digitalRead(IncbuttonPin);
DecbuttonState = digitalRead(DecbuttonPin);
checkIncButtonPress();
checkDecButtonPress();
if( bPress ){
bPress = false;
turnOff();
displayDigit(buttonPushCounter);
}
/*
for(int i=0;i<10;i++)
{
displayDigit(i);
delay(1000);
turnOff();
}
*/
}
void checkIncButtonPress()
{
// compare the IncbuttonState to its previous state
if (IncbuttonState != lastIncbuttonState) {
// if the state has changed, increment the counter
if (IncbuttonState == LOW) {
// if the current state is HIGH then the button went from off to on:
bPress = true;
buttonPushCounter++;
if( buttonPushCounter > 9) buttonPushCounter =0 ;
Serial.println("on");
} else {
// if the current state is LOW then the button went 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
lastIncbuttonState = IncbuttonState;
}

{

// if the state has changed, increment the counter

buttonPushCounter--;
if( buttonPushCounter < 0) buttonPushCounter =9 ;
Serial.println("on");
} else {
// if the current state is LOW then the button went 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
lastDecbuttonState = DecbuttonState;
