    screen program handles serial connection • Install Serial driver: http://www.ftdichip.com/Drivers/ VCP.htm • Open Terminal • (install the screen by “apt-get install screen”) • type “screen /dev/tty.usbserial-A7004C6X”
 underlined character differs by each gadget • to exit screen type “Ctrl A + k”

    the sensor value is > 250 • It works with specific LED but not works mine (for example) • Threshold should be based on the environment • Sensor LED data several times • Determine the threshold • Let’s change the program!
