Optical control music heart shape light suite 18 male light control
Working voltage: If all the sticks are adopted, you can use DC3V, if the color is different, in DC voltage 4.5 5v

This can control the 118 martyrs with ring flashing and music according to the light strength of the environment., in the stick, photosensitive Resistance as a Light Sensitive Element, the stronger the light, the lower the resistance value of photosensitive resistors.
Notes
Getting off the handle can change the way you control it, pleasant Pleasure 1、 3 and 2、 0400 hours, the stronger the light, the higher the serial pressure on the gnawing 7, this voltage is added to the reverse phase input terminal of the voltages comparator ic1a, when the voltage exceeds the same phase input voltages, ic1a low level, triode 8550 Conductivity, music chips and 118 madams are beginning to grow and flash on the ring maddening, pleasant billowing for loudspeakers, remove the short circuit caps of the gnawing strips., power amplifier for the tripole 5, the music chip's audio signal is amplified by the male 5 Drives passive buzzers to sound Conversely, if one is separately connected to another, the、 5 Foot and 4、 6 Foot, the darker the light, the higher the sequence pressure on the resistance merry. This turns into dark control. Other connections to the gnawing merry are not defined.

Adjustable resistance mastered 1 can be entered with the same phase voltage, getting the right light intensity for the petals, avoid being too high and too low. Music chips for positive touch, 2 feet for touch terminals, connect 2 feet to 1 of the power supply pin, it can make the music chip go along with the ring. Madam, madame, male, and female, the current limiting resistance of LEDs, rosters of Different Colors of LEDs, it is the same with the gnawing makers and the garnish with the maker and the madness with the same color as the three groups, a current-limited resistance of the same resistance value can be used. Due to different colours of madrasas, different voltages are available, so there is only one color in the sorcerer's petals, for instance, maltry1 6, pleasant1 6 can only be served with one color, if the color is mixed up, the high voltage of the conductor will not emit light. Getting the gnawing voltage. Relatively high,。 If you want to have the mishap and the merry mile, then the mishap will not shine, attention when instal
