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. • Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections.
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.

Description Description 3 2 8 1) On/off switch 2) Mode switch. 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. 5) RED output (3A DC max.) 6) GREEN output (3A DC max.) 7) BLUE output (3A DC max.
Connection Connection Incandescent lightbulb or halogen lightbulb: connect the lightbulb to the output R, G or B. Place a wire jumper for R4, R5 and R6. + - Polarity is not important. 3A /channel max (36W@12V). 12VDC 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. COM Anode Max. current consumption is 3A/channel.
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: Red LED, 1.7V drop, required current: 20mA Resistor calculation: (12V-1.7V) / 0.020 = 515 ohm (choose nearest value, e.g. 560 ohm) Resistor power rating calculation: (12V-1.7V) x (12V-1.7V) / 560 = 0.19W (choose a 0.
Use Use RGB-mode (mode switch into position ‘RGB’) This mode allows you to compose a desired colour by adjusting the level of each channel. 8) 9) 10) 11) 12) 13) 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.
Use 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).
