LED:s to master card
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 donīt 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 donīt 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.
Best Regards JouniJouni

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.
