MicroPython Tutorial VII

We have charged ahead in the last few tutorials and I thought this might be a good place to take stock. As I said in last tutorial you covered buttons, LEDs, sounds and images.

Lets take a few moments to review. The buttons we already named in the first tutorial. Here is reminder. You got 10 choices.

LEFT_DOWN
DOWN
RIGHT_DOWN
LEFT
CENTER
RIGHT
LEFT_UP
UP
BEACON
RIGHT_UP

Moving ahead beyond buttons, we talked about color, now in LEDs we have just four colors, although in honestly there are very few defined in MicroPython anyway. Here is a complete list for future reference, you can use all the colours with the colour sensor.

Color.BLACK, 
Color.BLUE, 
Color.GREEN, 
Color.YELLOW, 
Color.RED,
Color.WHITE, 
Color.BROWN or 
None

We picked sounds from a collection that downloads with the ev3dev brickman image. You can find the complete list by using the command “ls -lR /usr/share/sounds” obviously when you logged into the brick. At the time of writing I find these files.

robot@lima:~$ ls -lR /usr/share/sounds
