okay i'm building a fan speed controller using the pic 16f84a.
I have two inputs: i)infrared sensors to count the number of people (4)
ii) a temperature sensor
and one output: i) fan speed control
Okay i desperately need a circuit for the temperature sensor.
i'm using port b as the input...so i'm having problems with pin assignments.
if i use a lm35dz, i have to interface it with an adc 0804, so will i have enough pins (4) for my infrared input??
Please suggest the alternatives
