This micropython script for the pimoroni plasma 2350/2040, detects motion with the pimoroni tinyfx PIR sensor connected to the Qwic port then fades in a connected led string, it also waits for a few seconds of no motion detection, then gently fades out the led strip.
one small additional feature is that it will interrupt fade-out when motion is detected and captures the current brightness level, allowing LEDs to fade in from the interrupted level back to full brightness.
