+
+### 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
+```
