[Jouni]

Hello
First of all yeah i know that i shoult ask this question meaby on opencockpit forum,but because i think that here i get clearer and better answers i ask here. So i am planning to do on my EFIS ILS button. I have one led and the button,but i don´t know how the connecting goes .When i have two led legs i must connect them to Master card J2 Section that i know,but the thing what i don´t know is that how i connect them what cable i use?,and must them to connect also to ils switch?

If someone have somekind of example picture/tutorial i would appreciate if you could share that with me.

First off,

you have to connect your switch to either the J3 or J4 connection interface.
This is just a connection and will not provide power for your led.

You will connect your led to the J2 interface. J2 has 5 volts of power supplied.

To set up your led, you set it up like this;

On J2, Pin #1 has 5 volts supplied all of the time, dont use this.
Pin #2 is the ground that you will use for all of your LEDs.

So, the first led would be connected as;


Pin #3---------->Resistor------>LED---------Pin #2 (ground)

a second led would be conected like

Pin #4---------->Resistor------>LED---------Pin #2 (ground again)




Use the I/O confiquration;


Hope this helps.
