Hopefully someone can get me pointed in the right direction for this project. I've been reading so much my mind is spinning!
What I want to build is a 3 digit (7 sement) digit LCD display for a 0-5v input signal scaled from 0% to 100%.
It's an automotive application where I want to have a universal box that I can connect to a throttle position sensor output (0-5v) and be able to use a switch to set 0% at one voltage and then use another switch to to set 100% at a different voltage. Once set, the box would display 0-100% of the throttle position depending on the voltage.
It's a linear a/x+b scaling on one analog input driving a display with user set offsets.
If this were your project where would you start? Any tips/pointers would be much appreciated.
Thanks!
