LED Rainbow - RGB LED PWM Controller Construction - Easy To Build

Step 2Getting Organized - Identifying All The Parts

Getting Organized - Identifying All The Parts
Looking at the LED Rainbow board, you can see really just how simple of a design it is - but don't let the simplicity fool you as to how powerful it is.

The board measures only 2" x 2" (51mm x 51mm), is a double-sided design (meaning there are circuits or traces on each side of the board) and has a high-contrast silk-screen (the white lettering and drawing) on the top to indicate the layout of all the components and their orientation.

When assembling the board, you should do it with one component at a time, usually starting with the smallest and lowest components closest to the board. Keep in mind that some components are polarized or must go in a certain way.

Start by laying out the board and setting aside all the components in preparation.

Remember.. Full documentation on this product is available from the http://www.pcboard.ca/kits/led_rainbow/ support web site.

The parts needed to assemble the board are as follows:

Resistor 1/4 watt, 5% Carbon Film:
(3) 1K ohm (brown-black-red-gold) R1, R2, R3

Capacitors:
(1) 33uF 50v Electrolytic Capacitor C1
(-) Optional - .1uF C2
(1) .1uF C3

Semiconductors:
(1) 1N4002 D1
(1) LM78L05 5 volt regulator TO-92 Case U1
(1) LED Rainbow Processor U2
(3) STP36NF06 N-Channel MOSFET Q1, Q2, Q3

Sockets, Headers, Connectors and Switches:
(1) 8-pin DIP Socket U2
(1) PCB mount pushbutton switch S1
(1) Optional - DC Power Jack P1
