For example, using a momentary push button (normally off), 3 led and the logic gates needed, how can i do this?.
- 1st pulse. If all leds are off, turn on the first.
- 2nd pulse. If led 1 is on, turn on 2 and 3.
- 3rd push. If all leds are on, turn off all.
Of course, logic gates must be maintained in position between pulses.
I know how to do this using static switches, so there is always tension, but with momentary the logic of the circuit dissapears after the first pulse .... Any ideas?.
thanks
