This example shows how to display CPU usage with BlinkStick. Green = 0%, Amber = 50%, Red = 100%.
This tutorial requires psutil. Install it via:
pip install psutil
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(red=intensity, green=255 - intensity, blue=0)
