Hello to all.
I found sketch (on internet) for cat feeder with servo, and other sketch for counting button press with output on lcd 16x2.
I try to combine this two sketch in one and I have working (without error) code, but I have problem because sometimes servo start but I dont have count on LCD.
If some could please check where is a mistake?
Thanks in advance.
Robert
#include <Servo.h>
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
int a =0;
int e = 8;

const int servoPin = 9;
const int buttonPin = 7;
const int ledPin = 13;
void setup() {
myservo.attach(servoPin);
pinMode(buttonPin, INPUT);
digitalWrite(buttonPin, HIGH);
pinMode(ledPin, OUTPUT);
digitalWrite(ledPin, LOW);
myservo.write(180);
delay(1000);
myservo.detach();
