Step 3: PCB Design _Dip trace

Design PCB using Diptrace software. Download project files here :/*will upload soon using mobile now it's in my laptop */Download Diptrace software here:http://diptrace.com/download-diptrace/.

Step 4: NOTE

If you want to add components, or remove, or wish to do any change import project file to Diptrace, make a change and take a printout and then etch it .

Step 5: PCB Etching

Go through this link ..!http://www.instructables.com/id/Arduino-Just-Clone...

And follow etching steps.

Step 6: Components Placement

Place all the components in its corresponding place to solder

Step 7: Components Soldering

Place the components and solder using solder gun.

Step 8: Video
