I'm new at Arduino using. I can display analog values in LCD or control servo angle depending on analog value alone. But when i tried to do all three of them.....take analog values from LDR, control servo angle depending on the analog value & display the angle in LCD, I found some unreadable characters displaying on the LCD. Can somebody please help me to figure out the error in my code...
#include <Servo.h>
#include <LiquidCrystal.h>
Servo myservo;
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
int potpin = 0;
int val;
void setup()
{
myservo.attach(9);
lcd.begin(16, 2);
lcd.print(" SERVO ANGLE");
delay(1500);
}
void loop()
{
val = analogRead(potpin);
val = map(val, 0, 1023, 0, 179);
myservo.write(val);
lcd.clear();
delay(20);
lcd.print(val);
}
