led night light help

[pape21]

hi
i am now trying to make a new night light circuit and any help would be welcome.

that when pressed ON lights up a row of 10 leds ( amount doesnt matter as i can experiment making more or less leds once i have got the principle worked out)

i have been reading up on shift registers and binary counters because someone suggested they could work.

any ideas

If I understand correctly you want the LED's to turn on when you press the ON switch.
I am a firm believer in KISS (keep it simple stupid) and I don't know what shift registers would do in a common night light.

I built a night reading light out of 12V LED (ac/dc) array, an old lamp and a 12V wall transformer:

It draws only a little over 200mA.

So all you want is that when turned on, the leds light up ?

How about a switch wired in series with a string of leds ?

microcontroller based led night lamp!!

pape,
I would suggest a PIC based LED night lamp. No need of shift registers or complicated binary counter arrays. Everything built in

I think that what the original poster wants to do, is a light for a NIGHT club...just like the old light chasers.

Counters and shift registers may be used, but when I built one in the early 1980s a microprocessor was a better design choice.

With the improved and lower cost of today's microcontrollers, it would be an even better choice.
