Design a PCB layout of DICM system

Design a Printed Circuit Board (PCB) layout of the system is important to combine all the components that are used in one circuit. To design this PCB layout of this DICM system, the DipTrace software was used. In this software, the main component is the Atmega 328 which acts as the control center or the brain of the system was added first before starting to design the PCB of this system. After that, other components such as IR sensor, solenoid motor, DC gear motor, DC motor sprinkler, LCD and buzzer was added together to the main component which is Atmega 328. The design a PCB layout of DICM system is shown in the figure below. 

By design this PCB layout, we know how to put or added the components and adjust the component and the tracks on the circuit board to make sure there are no contact with each other. This is important before we print the real PCB circuit and start with etching process.
