Example: Display CPU usage

This example shows how to display CPU usage with BlinkStick. Green = 0%, Amber = 50%, Red = 100%.

from blinkstick import blinkstick
import psutil

bstick = blinkstick.find_first()

if bstick is None:
    print "No BlinkSticks found..."
else:
    print "Displaying CPU usage (Green = 0%, Amber = 50%, Red = 100%)"
    print "Press Ctrl+C to exit"
    
    #go into a forever loop
    while True:
        cpu = psutil.cpu_percent(interval=1)
        intensity = int(255 * cpu / 100)

        bstick.set_color(intensity, 255 - intensity, 0)
