I'm an EE. It's been about 20 years since I designed an embedded system, so I am very rusty on this stuff!
Last year I designed a system at work - a very specialized, multi-output power supply. It has four, independent outputs. We built a prototype. It works well. The customer now wants five more units.
For the second iteration I would like to incorporate an LCD into the unit. The display will show the voltage and current for each output. (For the current measurements I am using shunt resistors.) In addition, I would like the LCD to tell the user if the current is in a "normal" range for the load (less than 100 μA) or if the load is pulling too much current (greater than 100 μA).
So I need to make eight analog voltage measurements, do a little bit of math, and then and display their real-time values on an LCD. Nothing is high-speed, so a single ADC and 8:1 multiplexer for be fine.
What Arduino product(s) would you recommend for doing this?
