RGB Lights

The StudioBot has 4 RGB lights under the display. We can use these lights to show colours and signal output to the user.

The following code will set the light colours to red, green, blue with 2 seconds between each change.

import time
import board
from StudioBot import *

# RGB. values (Red, Green, Blue)
neopixel.set_color(255,0,0)
neopixel.set_brightness(0.2)

time.sleep(2)

neopixel.set_color(0,255,0)

time.sleep(2)

neopixel.set_color(0,0,255)

time.sleep(2)

To set a single pixel color

import time
import board
from StudioBot import *

#set pixel 1
neopixel.set_pixel(1,255,0,255)
neopixel.set_brightness(0.2)

The following code will show how to make the RGB lights swap colours after a given delay.

import time
import board
from StudioBot import *


neopixel.set_brightness(0.2)

def color_chase(red, green, blue, wait):
    for i in range(4):
        neopixel.set_pixel(i,red, green, blue)
        time.sleep(wait)
        
        
color_chase(255,0, 0, 0.1)  # Increase the last number to slow down the color chase
color_chase(0,255, 0, 0.1)
color_chase(0,0, 255, 0.1)
