Hello, a 15 channel Vu meter with peak hold feature. The microcontroller outputs are powered by MOSFET to control LED diodes. You can also use COB LED modules or 12V lamps instead of LED strips. It is also possible to control a 220V lamp using the MOC3020 module and triac.
CAUTION: If you are thinking of using a 220V lamp using a triac module, be very careful. There may be large explosions at high voltages, use a Fused Power Line and protective glasses before operating the circuit.
