    Dear all:

    I am David, this is a small app to show your Lego EV3 robot’s sensor value on screen, including touch sensor, color sensor (light level) and ultrasonic sensor. I use color.timer to poll sensor value regularly. You can of course use sensor event like above/within/below range to modify.

    (if this forum can support image upload would be wonderful, hah~)
