1 x 20cm Long 0 Interval 5 Pin Cord
Note
1. Dual 12 level music screen level ultra-small-size stereo level light, which can freely adjust the rise and fall speed of the light bar and the stop time and descent speed of the top lamp. Each lamp is separately provided with a current limiting resistor to ensure the brightness of the lamps of different colors is consistent, and to ensure that there is no light and dark change in the case where the lamp is much brighter. The signal input is isolated by the op amp to prevent the high frequency interference of the MCU from being inserted into the audio.
2. Classic color matching: 7 green + 2 orange + 3 red
3. The single-chip microcomputer uses time-sharing sampling, there may be two channels connected in parallel with the same signal, the amplitude of the two light bars may be different.
4. In very extreme cases, there may be very slight high frequency noise. Please pay attention to the power supply separately, and try to replace the lamp input line with the shield wire.
