Before construct the circuit in a breadboard, we decided to simulate the circuit first using software to get the  result. For this part (Simulation), Soo Ling will be the leader.

Firstly, we construct the circuit as shown in the project : 


For the relay, we connect the normally close pin to the LED to show the output.
After testing..........

DISAPPOINTINGLY,

            WE FAILED TO SIMULATE THE CIRCUIT DUE TO SOME ERRORS IN THE FILE!!!


It seem like we have to work harder....
