Know do not have any mp3/mp4 player quite common constantly are developing audio outputs for an amplifier with raising a complete sound system can be activated as a resource to be used player from the simplest and cheapest of the Chinese goods ramming a emulate their memory not sd card models used separately from the circuit printed circuit board on the mp3 player supply I’ve added the LM317 regulator for the 1.5Volt.

Result of displays in the form of two scales, which are estimated to judge the material goal.In addition, the screen is small scale level of response and the current supply voltage. PIC18F252 The program is intended for controller PIC18F252.The controller PIC16F873 (A) to this version can not be used. This is more demanding to resources controller. 252nd compatible controller on “pins” with 873 – m and can be programmed by the same programmer. The program workable only with korzinochnymi reels! R21 For this firmware needed zakorotit resistor R21 (in the old version of the scheme). In this version the appointment of buttons changed to read
