Arduino: 1.8.6 Hourly Build 2017/10/20 02:33 (Windows 10), Board: "Arduino/Genuino Uno"
c:\users\hp\desktop\arduino-nightly\hardware\tools\avr\bin../lib/gcc/avr/4.9.2/../../../../avr/bin/ar.exe: unable to rename 'core\core.a'; reason: Permission denied
exit status 1 Error compiling for board Arduino/Genuino Uno.
This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.
Please help me fix this problem. This is my code:
int redled = 6;
int yellowled = 9;
int greenled = 12;
void setup() {
pinMode (6, OUTPUT);
pinMode (9, OUTPUT);
pinMode (12, OUTPUT);
}
void loop() {
digitalWrite (redled, 1);
delay(9000);
digitalWrite (redled, 0); //stopped
digitalWrite (yellowled, 1);
delay (3000); // yellowled lights for 3 sec.
digitalWrite (yellowled, 0);
digitalWrite (greenled, 1);
delay (9000);
digitalWrite (greenled, 0);// greenled startstarts flashing
delay (500);
digitalWrite (greenled, 1);
delay (500);
digitalWrite (greenled, 0);
delay (500);
digitalWrite (greenled, 1);
delay (500);
digitalWrite (greenled, 0);
delay (500);
digitalWrite (greenled, 1);
delay (500);
digitalWrite (greenled, 0);
delay (500);
digitalWrite (greenled, 1);
delay (500);
digitalWrite (greenled, 0);
}
