LM3915 10 Led VU Meter Kit

Unassembled LM3915 10 Led VU Meter Kit
DIY Led Electronic Sound Music Level Light Indicator Soldering Training Circuit Spectrum Analyzer

The product is in unassembled state. The soldering process causes physical change. The soldering process prevents return.

     It is a 10 led VU meter board on which the LM3915 IC has been used. A VU meter is a circuit that displays light depending on the music sound intensity. The more the bass, treble and sound level of the music, the more leds light up. The product is sent in unassembled state. By using this module you can make your own VU meter. It is sent as a set together with pcb, pot cables sockets resistors and the lm3915 IC.

     The main purpose of the kit is the recognition of electronic components, the learning of the structure of electronics and  circuits, and soldering training processes. The student can build the circuit quickly, very easily and with fewer errors. It shortens the soldering training process considerably. The easy building of the electronic circuit is quite useful in learning and getting to like electronics.

     Soldering is started with the lowest profile, that is the smallest components. Afterwards it is necessary to move on gradually to soldering larger components. The numbers and names of the components are written on the pcb. The correct places of the components are found easily.
