Hello,
This is my first project in electronics so I will need a lot of advice
I want to output to the current wattage by an amplifier in my car to an LCD or LED display. I'm looking for a simple 3-digit display. I assume that I can tap into the car's voltage somewhere. How can I measure the current from the amplifier? Then, I can multiply these 2 results together to get my wattage.
Will I need a microprocessor to execute the multiplication? Also, I'd like to have a looped timer set to about 250 ms, so that it delivers the output on these intervals.
It's probably a simple project for you guys...but this is new to me and I hope I can do it!
Thanks a lot,
