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 ::

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 ..!

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 !
