Mạch đèn LED 16 bóng ánh sáng xanh nháy theo nhạc có màn hình hiển thị âm lượng

Description:
Size: 50 mmx110mm, blue light.
Two fixing holes diameter: 3 mm pitch: 100 mm
Signal input range: minimum 300 mv. Maximum 5 v (not too strong signal)
Power supply voltage: DC 8 v to 12 v
Maximum current: about 70 mA

feature:
Two buttons S1 and S2, long press (more than 1 second) and short press (less than 1 second and more than 0.2 seconds). The key function is quite simple.
S1 adjusts the strength of the input signal in the normal display mode. Cyclically reduce the number of input signals by clicking, and automatically return to the beginning according to the end. S1 In the brightness adjustment mode, press increased until the highest level og brightness.
S2 is used to select the display mode in the normal display mode. The same click conversion cycle will automatically return to the last one. S2 In the brightness adjustment mode, press one level until the lowest brightness. S2 In the normal display mode, long press Enter brightness adjustment mode, S2 in brightness adjustment mode, long press will save and return to normal brightness display mode.

Wiring precautions:
1. Do not use AC power and do not occupy high voltage.
2. -/+ indicates power supply,-indicates negative input power, and + indicates positive input power; the signal strength is not too high, the signal strength on the headphone jack is generally provided to it, do not use a power amplifier to output a signal that is too strong Will make the circuit worse.

3. The audio signal 3 line is label R L G, it is the right channel signal, the left channel signal, labeled ground (ie negative power circuit board)
