OK, so I know that I've taken some beating and criticism. Mostly because I haven't done anything like this before so first things first.
Thank you for your input and knowledge. I wouldn't be this far without it.
I would love additional feedback, problems, thoughts on what I have going on here.
-
Vin is from an automotive battery / charging system (9.6 - 15.8V)
-
Arduino power supply should be outputting 8V (trying to keep current at a minimum to prevent 7808 from heating up too much).
-
RHEO1 goes to the OEM dimmer on the car. It's Range is 0-10ohms
-
I've figured 5mA of current going to the OEM dimmer giving me a Voltage Range of 0-50mV.
-
OP amp 741 is to be used to Amplifiy the Voltage Range ~50x to 0-2.56V to be compared against the Internal Reference.
-
The white LED driver (Q1) is meant to send +12 PWM to White LED's which would be grounded where they are.
