Versatile RGB LED PWM Driver

Step 2 Identifying the kit contents

All the parts shown are supplied in the full kit available from http://picprojects.org.uk/shop/

The kit is fairly simple to construct, but you will need a soldering iron, solder, side cutters (long nosed pliers can be usefull too). If you've never soldered before, have practice on a scrap board before attempting assembly of the kit I also recommend checking out this Instructable 'How-to-solder' http://www.instructables.com/id/How-to-solder/

The board should be assembled starting with the smaller parts and working up to the larger ones. Install and solder into place one component at a time.

The MOSFETs Q1,Q2,Q3 should be left in the anti static packaging until you are ready to install them onto the PCB.
