How to display ADC voltage on LCD Display

MarkT:

  float voltage = analogRead (pin) * 5.0 / 1024 ;

Will be a start. Then find the right options to print the 3 dp's.

That won't work right
Should be:

  float voltage = analogRead(pin) * 5.0 / 1024.0;

Note the .0 on the 1024 to force it to a float value.
