Circuit construction by simulation
After we confirm all the components that we will used, we proceed to circuit construct by using software ISIS Proteus.
IC Selection
We have done some reseacrh regarding IC selection on which one should we choose between AT89C52 or AT89S52. During our simulation we used AT89C52 and 8052. We have observed the power consumption and connection port between these IC and other configuration. AT89S52 The 89S52 has 4 different ports, each one having 8 Input/output lines providing a total of 32 I/O lines. Those ports can be used to output DATA and orders do other devices, or to read the state of a sensor, or a switch. Most of the ports of the 89S52 have 'dual function' meaning that they can be used for two different functions. The first one is to perform input/output operations and the second one is used to implement special features of the micro controller like counting external pulses, interrupting the execution of the program according to external events, performing serial data transfer or connecting the chip to a computer to update the software. Each port has 8 pins, and will be treated from...
