This DIY Kit contains 118pcs super bright warm white LED (brightness 2000-3000mcd), 7pcs blue LEDs and 8pcs pink LEDs and array into a butterfly-shaped pattern and can presents a multi-state shining lantern pattern,even in the day,it still has the obvious effect.Besides,it has 13 music(tone music) which is very active and interesting,there is no doubt that this kit is a kind of fashionable and attractive electronic products.
This suite is easily to assemble, the program has already written in MCU, it can be worked when assembled.It will be a wonderful gift to express your love and friendly in Christmas, New Year, Valentine’s Day, and other festivals.It can also used as household lighting,it can changes shape and brightness automatically.( Maximum power maximum about 4W, the actual feeling is less than 3W LED energy-saving lamps, the lighting is warm, can be totally used as lighting, if you want more lightness, you can reduce the current limiting resistor, the power can reach more than 8W, on the contrary, If your character is too bright, you can increase the related limiting resistor by yourself.)
2. Assembly Notes
1>. There are five short-circuit connctor on PCB which have been marked J1/J2/J3/J4/J5.User can weld them by pins that cut from resistor or LED at first.
2>. Assembly steps: All components should be installed followed by the small to big, and try to follow the principle of circuit board, the short cable can be replaced with excess pins of resistance.Pay attention to cut excess pin slightly and don’t pull the pin.The false operation will cause the circuit board copper foil broken easily,result of the the installation failure.It needs stable power supply,the working current is above 800mA.
3>. Non-remote kit isn’t equipped with remote receiver and remote controller,and the corresponding elements are not installed.
4>. Make sure the power supply is above 3.7-5.5V 0.8A,pay attention to the direction of positive and negative.There have mark in “+” “-“ of all LED,electrolytic capacitor,remember do not put is reverse.
