WEEK 8:Schematic Explaination

WEEK 8

In this week I will explain  how the  circuit function & operating.



         LCD DISPLAY SCHEMATIC DIAGRAM




               In this circuit diagram I will explain how the circuit function.The main component in this circuit is PIC16F877A the functions is to control all process and  it must be program it.The input will come  into analog signal and change to digital signal,how the process happen?The process must pass through 3 step  first sampling,quantars, and last one are  encoding.After that the output will come out to the LCD display.The power supply  that use in this circuit are 5v,we using adapter as our power supply.





TEMPERATURE SENSOR SCHEMATIC DIAGRAM






                 In this project contains 3 circuit board to make this project function.firstly is temperature sensor schematic as our input as we can see at the diagram have amplifier,resister 100k,temperature sensor and preset to control the sensitivity of the temperature sensor.To operating it  the temperature sensor will sent input to amplifier and  amplifier will amplifir  the signal  low to high signal to get the good signal or wave
