LED Delay.

Hi all quick question regarding LED,s. Maybe its a dumb question but is there anything on the market that can delay the led from lighting up for say 5-15 secs once powers supplied to them. Im asking this as a bit of a cheat for the landing gear indicators that light red/green when gear is going up or down.
Cheers.

Hi Rich,
There is a way useing electronics, but output from Fsim can be taken and used to drive your leds when gear is fully extended, in transit and fully retracted.
What i/f are you using, that might give us all an idea of how you could achieve this action.

Hi les
Thanks for reply
At the moment im using an old joystick card with 2 basic switches onit done though fsuipc. so at the mo i just have the green leds conneted via the gear down switch if you get what i mean. so when lever is down on the gear down switch it also makes connection for all 3 green leds. Maybe some kind of delay switch/relay or somthing i need. I understand that with proper interface cards i can program the leds to come on as appropriate, it was just a temp/cheat until i start the main build oneday.
Cheers

Hi Rich,

If you are thinking to a hardware solution, you may consider building a little circuit using a NE555 (or SE555) in monostable mode. There a many exemple on the Net ; here is an exemple :

Hi Rich,
I thought that was your case. My thoughts are the same as Patricks, use a 555 timer. Here are some timer circuits that may help.

Thanks guys will have a look into them cheers for the help..

The link below shows a method to drive the green and red gear indicator lights with appropriate delays. It is triggered by the switch of the gear lever.

I'm a little late but you could use the circuit I made for this GA thread here.
