Title: Connecting illuminated av to Emerald Post by: Rashimotosan on December 06, 2018, 02:47:31 PM I'm trying to figure this out and the diagrams I'm seeing are a bit confusing. Does anyone know how to wire an illuminated AV switch to the emerald board? I have a RGBW led and I want to connect it to a red illuminated black AV switch. Also do I need any sort of resistor on the connection to the switch itself?

There's normally two sets of pos and neg, one for the button and one for the LED so find out which sets are for the button and the LED first. The Positive and negative for the button would go to the board but you have to connect the positive and negative wires for the LED into battery and wire either the positive or negative into a resistor. The resistor that you need will depend on the color of the LED in your AV switch Title: Re: Connecting illuminated av to Emerald Post by: Rashimotosan on December 06, 2018, 05:28:57 PM How many prongs do you have on that AV? 3? 4?

Assuming you're using the Emerald or Diamond controller which outputs 7.4 Volts so doing the math, you'll need the 270ohm 1/4 W resistor for that AV switch. You can find one off of TCSS' site and yes it's 270 ohms 1/4 Watt resistor Title: Re: Connecting illuminated av to Emerald Post by: Rashimotosan on December 07, 2018, 08:00:42 AM Forward voltage is 2 V and runs at 20 mA.

At least I know now I DO need a resistor and won't blow something. Title: Re: Connecting illuminated av to Emerald Post by: Infinit01 on December 07, 2018, 03:10:59 PM Omg thank you!

That was a really good question and when I wired up my own AV, I was glad that I know Ohm’s Law and it’s not because I’m Asian and I’m good at math. I just like Ohm’s Law, that’s my excuse anyway... Lol Let me know how it goes and shoot questions if you have them |
