Part I: The voltage divider.
Because eight bit mircocontrollers lack floating point instructions using floating point can consume a lot of processor cycles.
In this article I will illustrate how to measure up to 100VDC with an analog to digital converter, ADC, with a positive voltage reference of 5V, +Vref, and a negative voltage reference at gnd -Vref.
The input to the the ADC must never exceed the 5V value of +Vref. We can use a simple voltage divider to accomplish this. To specify
