How to stop LED 13 pin blink at initialization of Arduino MIcro?

Hi all, I'm having a problem that Micro's LED PIN 13 is blinking when I power the Micro and blinks off after that code starts running, It should not blink When I power the Micro for the first time, I'm using 13 pin for other purpose.

Kindly assist me! Thanks

  • Use an ISP programmer to program your code. This removes be blinking bootloader.
  • Use pin 13 as an indicator and some other pin for your “other purpose”.
