Page 3: Assembly Hints
Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a small tip. - Page 4 Assembly hints 1.3 Soldering Hints : 1- Mount the component against the PCB surface and carefully solder the leads 2- Make sure the solder joints are cone-shaped and shiny 3- Trim excess leads as close as possible to the solder joint REMOVE THEM FROM THE TAPE ONE AT A TIME ! DO NOT BLINDLY FOLLOW THE ORDER OF THE COMPONENTS ONTO THE TAPE.

Select between ‘RGB’- and ‘Effect’-mode ‘RGB’-mode: Red, Green and Blue output levels can be individually adjusted by means of the up/down buttons ‘Effect’-mode: Allows to choose between 11 built-in effects 3) Output indicator leds. 4) Power supply connector.
- Page 9 LED-strip with common anode (+) : Connect the common anode to the (+) of the 12VDC power supply. Connect the cathode (-) of each colour to the (-) of R,G or B on the K8088. Place a wire jumper for R4, R5 and R6.
- Page 10 Connection LED: LEDs require a series resistor (R4, R5 or R6) Determine led voltage drop (Check manufacturer datasheet). Rule of thumb: red: 1.7V, green: 2V, blue: 3..4V). Next, check required LED current. Example: 12VDC Red LED, 1.7V drop, required current: 20mA Resistor calculation: (12V-1.7V) / 0.020 = 515 ohm (choose nearest value, e.g.
- Page 11 RGB-mode (mode switch into position ‘RGB’) This mode allows you to compose a desired colour by adjusting the level of each channel. RED-level down RED-level up GREEN-level down GREEN-level up BLUE-level down BLUE-level up Memory: Once you have composed a colour, you can store it in memory by flipping the mode switch to ‘eff'. Next time, when you turn on the controller with the slide switch set to ‘RGB’, it will revert to the colour you’ve composed.
- Page 12 Effect-mode (mode switch SW8 in position ‘eff’) This mode allows you to select one of the 11 available effects, using the buttons (8) and (9) Effect # Description Select a static colour by means of buttons (12) and (13). Static colours Colours: Red - Green - Red/Green - Blue - Red/Blue - Green/Blue - Red/Green/Blue Sequenced colours Same as above, but automatically sequenced...
