week 7

Title of the activity : Designing the PCB layout for the transmitter and the receiver circuit        





          Before this,the circuit of the project are constructed on breadboard. To proceed the project, the circuit need to soldered together on PCB board. The design of PCB layout was designed by using the Diptrace software. Figures below shows the layout of PCB for the transmitter and the receiver.

         For the receiver part, the circuit of rectifier and regulator circuit  was added to produce the DC voltage. The circuit regulator is used to maintain 5V of the rectifier output. Figure below shows the layout of the circuit.
