Step-by-step, easy to follow instructions on the building of a LED Rainbow RGB LED PWM Controller. Only a minimal amount of parts are needed, along wi...
The LED Rainbow is a dedicated Pulse Width Modulation (PWM) controller which generates color changing effects with RGB LED lighting products. The circ...
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 i...
The first step in laying out the kit is to have a clean work surface, with your components set aside and easily identifiable. We will not be going in ...
Position D1 (1N4002) diode. You will notice a silver/white bar on the diode. This is the Cathode and should match the silk-screen on the PCB. Ensure t...
Now place the LM78L05 Regulator at U1. Notice that the device has a half-circle flat side on it. The flat side should face towards the bottom of the b...
We can now move on the C3, the .1uF Capacitor. This capacitor is not polarized, so it can go in either way. Solder in C3 now.
The next component to go in will be C1, a 33uF Electrolytic Capacitor. It is important that you watch the markings on this component. Normally, the ne...
We now move on to the three resistors at R1, R2 and R3 which are 1K ohm resistors and have a color code on them of brown-black-red-gold. Resistors are...
It is now time to install the push button switch at S1. This switch is not polarized, but it will only fit into the board one of two ways. The switch ...
Now position the 8-pin IC socket at location U2. This is the socket which will hold the PIC Processor LED Rainbow controller. You can now solder into ...
It is now time to install the three N-Channel MOSFETs (STP36NF06) at Q1, Q2, and Q3. MOSFETs are sensitive to static, so use care when handling them -...
We can now move ahead and install an optional Power Jack at P1. This jack allows for a standard wall adapter to be used to power the LED Rainbow PCB. ...
The final step in the assembly of the board is to insert the LED Rainbow controller into the socket at U2. The controller must be placed into the sock...
Congratulations. You have finished building your LED Rainbow controller system. Now you can connect up your RGB or individual Red, Green and Blue LEDs...
We have prepared a short video of the LED Rainbow in action. This is an example of building the unit into a standard home lamp with a frosted globe on...
