his three color SMD LED, colorful, color flexible configuration, prefabricated a of color scheme, can set a color scheme specific to the color of each point, there are design can choose, can adjust the brightness, the sensitivity adjustable, can set the infrared remote control self learning convenient control, infrared remote control need to match, only supports the /C, this format is more common, can take home try television, set-top boxes. I get home in nine receiver remote control, remote control, TV Tmall remote control and a waste of VCD remote control test can be used, remote control of home electric fans and air conditioning remote control test can' use). Size: length: 100 mm width :35 mm thickness :12.5 mm, installed two hole center distance : 52 mm ,hole diameter: 3.2 mm (installation note mounting holes around the wiring insulation plus insulation gasket) Power supply: DC5v -6 v / 250 mA(Maximum current is LED the whole amount and the highest brightness, generally less than 100 mA); Audio signal: pick up the three lines on the headphone jack, respectively is a signal Ground (together with the power of the board negative) )left sound channel, right channel. Functional status and buttons operation: K1 and K2 two buttons, press is have short press and long press. The following statement didn' explain the long press is said short press: (1). level display status: according to the last time after the power supply power, the brightness of the former, figure, color scheme and sensitivity to normal level.This state the button function: K1 / show pattern selection click in a pattern, pattern at of the cycle from the very beginning. K1 long press/to enter the pattern of color scheme selection state. K2 / sensitivity select click change sensitivity level, the order is the highest sensitivity,etc.The lowes sensitivity, sensitivity automatically return to the highest sensitivity. K2 long press/entered into a state of brightness adjustment. (2). Brightness adjustment status: the left section 24 of the bright display 8 red 8 green 8 blue, on the right shows the current brightness (red), 3 pieces according to grade 1, Toatl grade 8.This state the button functions: K1 / click the higher brightness level, the highest is all bright.K1 long press/return level the brightness of the display status and return before entering the set. K2 / brightness click on the lower level, the lowest level is the low end of the three led light.K2 long press/save the brightness of the set and returns the level display status. (3). color scheme selection state: left and right sides of each led all bright led displays the current color keep on top of the mode leds ( said the color of the point). This state the button functions: K1 / click the show next prefabricated color configuration scheme, the order is a scheme, the current program, the last a prefabricated scheme, (note that when the factory is empty, that is, all black, the need to define the color of each dot), prefabricated plan 1, so cycle.K1 long press/to save and select the current scheme return level display state.K2 / press with K1 instead choose order.K2 long press/to enter a custom color configuration status. colour: green Material: plastic Package Contents: 1 x Assembled 5V RGB MCU Adjustable Display Pattern 24 LED VU Level Indicator Meter Dual Channel Only the above package content, other products are not included.
