Hello all,
I am working on a bluetooth project. I plan on hardwiring a bluetooth receiver to a factory stereo to keep that simple original look. I was talking to a professor the other day about suggestions for relay( circled in red), and he suggested that I use a solid state relay. In my search for one, I cannot seem to find anything that fits my needs. I would like to go with a SSR as it should be smaller than an automotive EMR. Please recommend one for me.
A little about the project. original source will be 12V, with a 5 volt regulator to power 2 usb female receptacles. 1 usb(usb at top of pic) will be for charging or whatever, but the second usb(bottom of pic) will be connected to the bluetooth receiver. The plan is to take a 8.3V signal when the tape button is pushed to activate the relay and power on the second USB. So pretty pretty much when i press tape button, bluetooth will turn on, if the tape button is not pressed, the bluetooth will be off.
As for the LED, online resistor calculator suggest that I use 1/8W 150ohm resistor, but I can get 1/4W 150ohm resistor from school. Can I use the 1/4W resistor instead of 1/8W?
Thank You,
Charley
