Vu meter diy kit11/19/2023 Strip show after+the disappearance of the vertex travelĤ. Strip show+after vertex travel whereaboutsĢ. positive and negative reversed will cause light damage level.ġ. Operating voltage consume: 7-12V / 100MA. User can freely adjust each light bar and the main vertex of the real speed of light, with the most suitable for their own display.Īudio input through the TI original signal isolation, the maximum to avoid the single-chip high-frequency interference to an audio circuit in series.ĭifferent colors of light alone provided a current limiting resistor. The sampling time-sampling, so that there is dual-channel simultaneous parallel input signal changes fast, the amplitude of the two light bar display may vary, this is a normal situation. MCU TYPE 12 LED 2CH Channel Audio VU Meter LED Level Sound. LM3915 10 LED Audio Level Indicator VU Meter The 10k Ohms blue variable resistor is a adjuster of input which how user satisfy the level of LED lights and their output of amplifier matching for indicator.Ĭheck prices on Shopee or Check prices on Lazada Schematic Diagram credits image to leetsacademy *Minimum number of external parts required. *Not necessary diode or transistor for ALC *logarithmic indicator for 5-dot LED of bar type. *High gain rectifying amplifier included(Gv=26dB) It is suitable for AC/DC level meters such as VU meters or signal meters. The KA2284 is a monolithic integrated circuit designed for 5-dot LED level meter drivers with a built-in rectifying amplifier. Brightness level in amplitude can be adjusted The ALC circuit without telescoped diode or transistorĤ. This package LED indication logarithmic 5:00 KA2284 integrated circuits as the core, Which is characterized as follows:ģ. Melody audible, visual music! Five-point LED audio level indicator kit
