Follow these simple instructions to build you own RGB LED PWM driver. This easy to construct, versatile driver board will allow you to make your own RGB LED driver that can be built into all kinds of lighting effects. It doesn't need DMX or any other external controller to operate, just a suitable power supply. The firmware is available as a free download and the sequences fully customizable, so if you have access to a PIC programmer you can create your own range of sequences for use with the kit.

However, if you just want a ready-to-go driver you can buy a complete kit of parts including pre-programmed PIC with a range of effects; a short kit comprising the PCB and a preprogrammed PIC or the PCB only, whichever best meets your needs.

All available from the PIC Projects Store http://picprojects.org.uk/shop/shop.htm

More details of this project, other RGB drivers and the firmware download can also be found on the PICPROECTS website http://picprojects.org.uk/projects/picprojects.htm

There are others around who offer a similar kit based on our firmware code. We suggest you stick with this one, the original customizable RGB LED PWM Driver from the people who developed the PIC firmware.

Step 1: Overview

This driver can be used with a large range of RGB LEDs, LED array modules or indvidual LEDs.

The firmware programmed into the PIC microcontroller generates an 8 bit resolution PWM signal on 3 output channels. The outputs control three power MOSFETs that when connected to Red, Green and Blue LEDs are capable of generating a huge range of colours and effects.

The kit comes complete with a pre-programmed PIC microcontroller that includes a range of colour fading and strobe effects. User control is via a single push button switch which has three functions:
1. Short press, Freeze / Run the current effect
2. Double press, steps to the next effect
3. Long press > 1.5 seconds puts the driver into standby , holding the switch for a further 1.5 seconds turns it back on.

The current freeze / run state, colour and sequence are all saved to NVRAM so the driver always powers up using the last sequence and state.

Nice Instructable but why is switch 2 not in use?<br /> Thanx, Jaap<br />
