Description The colour-changing LED on this kit turns on when it goes dark and stays on for a period of time. This makes a good night light and because the LED is only on for a small amount of time the batteries last much longer than a light that is on all night. There is an onboard trimmer to set the light level at which the LED turns on and another trimmer to set how long the LED stays on for. https://elecena.pl/product/19046577/kitronik-timed-night-light-project-kit 2021-07-12 https://elecena.pl/product/19046577/kitronik-timed-night-light-project-kit 2025-07-09
