Simple circuit in a flashlight to alternate between steady and blink with push button.
Could anyone tell me what the circuit in a led flashlight is that allows to it be alternately off, low beam, high beam and blinking with just a push button. Is there a way to achieve this without a micro controller. All the responses I can find involve the use of something like an arduino. There has to be a simple circuit for changing through the modes with just a button as the lights are quite inexpensive. Thanks a lot.
