INTRODUCTION

As the theory and practical is combined, i did a simulation on every circuit part and combined it by using Proteus software. But in certain part of the circuit, the simulation cannot function well as it was due like monostable operation and astable operation. This maybe in simulation, the input need to be prisely correct to 2/3 of Vcc to make those circuit operate well. But in practical those circuit working well.

SIMULATION

Proteus v7.6 is a window base is more practical to use to simulate the circuit as its has LDR component inside it. But for taking the measure of either voltage or current the best software is Multisim 2001.
By means, i used two software for this project to be success. Multism to measure the voltage and current while Proteus for circuit operation.

in multisim, only a part by part can do in simulation as its cannot handle larger area of the circuit  (combination circuit)

not every characteristic (by refer tp previous week) can be made in simulation. in this case Schemitt Trigger cannot be done as in simulation, as the current flow is fast (there no error of equipment in simulation)
