8 leds with one push button

[rnzb]

dear all
i have to make a simple circuit with 8 leds and one switch button
when i push the button first led will turn on
when i i push it again the first led will turn off and the second will turn on
and so on till 8

also if available i want to add this feature
whenever i push the button it will not turn on the led directly i need to delay 2 secs or 1.5 secs and keep pushing till the flash lights up

and i want another button to turn on and off all the circuit

your help will be appriciated
thank you in advance

Use a PIC, and program it accordingly - by FAR the easiest way.

thanks for fast reply
can you guide me what is PIC and how to use this
and what is FAR ?

i just want the map and i will apply it

A PIC is a micro-controller - an entire computer in a small chip.

Here is a simple circuit that does a similar thing:

Although you couldn't do the delay with this method, a really easy solution is to use a 4017 chip.

look at the #21 post

delete the 555 timer if you want to use button

download an open it using ExpressSCH

Unless you never used a pic before!!!

In which case it's time to learn!
