### LEDs
The camera has a dual color led (red/blue) connected to gpio's 50 and 51.
To control those leds you can use the /sys api:
```
# make the gpios accessible
echo 50 > /sys/class/gpio/export
# and set direction (only need to do once)
echo out > /sys/class/gpio50/direction
echo out > /sys/class/gpio51/direction
# turn on blue led
echo 1 > /sys/class/gpio50/value
# turn off blue led
echo 0 > /sys/class/gpio50/value
# turn on red led
echo 1 > /sys/class/gpio51/value
# turn off red led
echo 0 > /sys/class/gpio51/value
```
