LM341 is a new component for me. Been looking at some circuits online and this one looks fun and useful. It keeps an LED off until the supply voltage rises above a certain point. A couple resistors, or a trimpot, as used in this video, can be applied to the reference pin to determine the minimum supply voltage to turn the LED on. I include many voltage and current measurements with my multimeter. #electronics
