Consider the following program which intend to blink two LEDs connected to Arduino board (Pin 13,14 has two LEDs connected) once uploaded into the microcontroller on a Arduino board and powered it up. void setup() { pinMode(13, OUTPUT); pinMode(14, OUTPUT); } void loop() { digitalWrite(13, HIGH); delay(1); digitalWrite(14, HIGH); delay(1); digitalWrite(13, LOW); delay(1); digitalWrite(14, LOW); delay(1); } But it was observed that LEDS does not blinking once uploaded into the microcontroller on a Arduino board and powered it up as expected. Select the program which correct this problem.
