Hands-On ROS for Robotics Programming

LEDs and blinkers

There are two LEDs on top of the board that simulate GoPiGo3's eyes. By running the following block of code, they will change their color:

colors = [ (255,0,0), (255,255,0), (255,255,255), (0,255,0), (0,255,255), (0,0,255), (0,0,0)]for color in colors:    GPG.set_eye_color(color)    GPG.open_eyes()    time.sleep(0.5)

The blinkers are two small red LEDs underneath the red board at the front. The following code makes them blink 5 times:

for i in range(5): GPG.led_on("left") GPG.led_on("right") time.sleep(0.5) GPG.led_off("left") GPG.led_off("right") time.sleep(0.5)

Check it visually, and be aware that no message appears in the console.
