Mashinasozlik texnologiyasi va avtomatlashtirish

Voltage at pin in milliVolts = (reading from ADC) * (3300/1024)
Ushbu formula 0-1023 bo`lgan sonli qiymatnin 0-3300mV (= 3.3V) bo`lgan kuchlanish qiymatiga aylantirib beradi.
Keyinchalik, millivoltni temperaturaga aylantirish kerak, bunda quyidagi formuladan foydalanamiz:
Centigrade temperature = [(analog voltage in mV) – 0,5] / 0,01

1. 
   temp = analogRead(2)*5/1024.0; - Analog kirish sonli qiymat signalini kuchlanish signaliga aylantiradi.
   
2. 
   temp = temp - 0.5; va temp = temp / 0.01; - esa millivolt qiymatini temperatura qiymatiga aylantirib beradi.
