echo low > /sys/class/gpio/gpio107/direction
echo 199 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio199/direction
echo 1 > /sys/class/gpio/gpio199/value
usleep 150000
echo 0 > /sys/class/gpio/gpio199/value
usleep 1000
echo 1 > /sys/class/gpio/gpio199/value
echo 107 > /sys/class/gpio/export
