Hi. I'm want to turn off all the blue led on maker uno. Does someone know how to do it? I will pair maker uno with i2c lcd so i don't need the blue leds

Hi 9w2ver,

The LED in Maker UNO can't be disable. It is permanent in the board unless you dissemble it. :) Any reason you want to disable the LED? The LED didn't disturb I2C pins (A4, A5), you still can control the I2C LCD. To light off the LED, just set it to OUTPUT LOW.

Ouch! I'm also looking for this. I have done a project and would like to mount the maker uno. The LEDs are quite disturbing. If I were to set all the pins to low except the ones I need it to be HIGH, would there be any issues?

If by setting the pins to LOW (just want to turn off the LED) is not affect your system operation, go ahead, no problem. :D
