1. Power
In doing this work when the audio signal from the input
module output signal is a sine wave, the signal because to the
interference signals or how difficult it is to have the best
sound quality in the module.The circuit of the light in the
course of the experiments and connection were carried out
successfully.Circuit Power supply have been successfully
modified after a fire in the past week. An error occurred in.
week of not having to calculate all the currents of the circuit
design to the current value of the too many.
