Hi, Im on a mission! i want to hit a button, and then a series of leds light up, one after the other (1 on at a time) And when the last led lights up, it awaits the next button press. Im using a simple 555 monostable circuit for the trigger, timing (of a secondary circuit) and the providing of a trigger. From what ive investigated i have aquired some 4017 chips, but they are not performing the way i want (every button press lights the next led) should i set a second 555 astable circuit to trigger the 4017, and then find a way to stop the 4017 at the end of the sequence, or is there a simpler way? thanks kelvin.
