The 2 LEDs on the EV3 are connected via GPIOs (2 each). Each LED has 3 colors: red, amber and green. Turning on a single GPIO will change the LED to red or green. Turning on both GPIOs will change the LED to amber.
| LED | GPIO | Description |
|---|---|---|
| 0 | 6-12 | Right, Red |
| 1 | 6-14 | Right, Green |
| 2 | 6-13 | Left, Red |
| 3 | 6-7 | Left, Green |
##Device Driver We are using the existing leds-gpio driver. This provides a standard interface for using the LEDs. The LED devices are defined in board-legoev3.c.
