I have got a project, it has a dip switch which control the scale of 0 - 5.
After pressing the pushbutton switch, the timing of the led will light up depending
on the scale.If the scaled is 0 to 3, the green led flashes for 16 times.
If the scale is 3 to 5, the red led flahes for 3 x scale times and after which green
led is flashed for the next (16-(3xscale)) seconds.
For the led timing, i can use binary adder(74283) and the synchronous 4 bit up/down
counter with mode control(74191) I also need a J/K ff with reset & clear function right,
to check & reset the led.
Do i need a 4 bit comparartor (7485) to know whether the scale it is in is 0 to 3 or 3 to 5?
What chip shouild i use to connect at the dip switch or puish button switch?
