I have an exsisting circuit which, using a relay, switches between two channels. I want to add two RGB LED's to the circuit so that when the relay is off one LED is white and the other is blue. When the relay switches on I want the colors to switch on the LEDs.
My qustion is can i use the exsisting 8v supply on the relays to power and switch the LEDs? And do i need to use some type of MOSFET or JFET to switch between the different colors? I'm trying to save cost by not using another relay in the system.
I know I'm going to have to figure out the correct values to turn on the different wavelengths.
Any ideas on how to go about this?
Thanks
