ADC lcd display help

Why would that read 205, instead of 204?

Thanks for catching that and I apologize for the confusion.

I changed the article to

10 bits ADC = 0 to 1023, 1024 steps.
At 5.0 volts one volt of input will will read 204. (204.8 actually)
But we will use 205 for accuracy.
204 * 5 = 1020
205 * 5 = 1025

Hope that clears things up a bit..
