How To Make Remote control Mp3 Player At Home



It is to make Usb Mp3 Player at home with Usb Mp3 Player Module. This Module can read MP3 files from a USB thumb drive and play it for you. I Found a compact sized USB Reader circuit, which has a Sleek IR remote control, Comes with small LED Based Display.(LED Based Seven Segment Display). I bought it from a local store in Bhiwani Haryana. I also purchased a IR receiver which was Damn cheap and you can control the played audio. IR module has points as "IR" , "Gnd", "5V" when using from Left to right. There is no need for connection other buttons and wires if u use IR sensor because after that u can do everything with module via Remote Control. The main attraction is its cost. The board cost only 120 Rupees ( 3$). Total cost f Equip so far. Rs.150/-

Main Parts:
  • Usb Mp3 Module with Remote (See screenshot)
  • IR Sensor with Metal case (You can buy it from any TV spare parts shop)
  • 0-9 AC to Dc ( 1 Amp.) Transformer (You can buy it from any TV spare parts shop)
  • Audio Board 6 Volt to 9 Volt (You can buy it from any TV spare parts shop)
  • IC 7805 with 1000MFD 16 to 25 volt Capacitor (You can buy it from any Tv spare parts shop)*
  • IC 7805 is used for convert 9 volt in 5 volt that is require for Usb Mp3 Module and your audio board require 6 volt to 9 volt so there is no need to connect Your audio board to 5 volt supply only 5 Volt is only for Module circuit.
  • IN 4007 Diodes (4)   for filter 0-9 power supply
  • One blank project matrix PCB Board for mount IC 7805 Power Supply and other components on it.
  • One USB socket for connect Pen Drive (Usb) to module
  • One Audio Jack with pin for connect speaker to you audio board
  • One Volume control (10 K) for control audio output


The board circuit diagram is so simple that there are a very few connections. Some of the connections are:-
Connector-1
3.3V - Power for IR sensor (Same as in Picture-3)
IR - IR data line of IR sensor
GND - Ground of IR sensor
PLAY - switch connection for play
VOL- - switch connection for vol -
PMCH - switch connection for mode(Radio/USB)
VOL+ - switch connection for vol +
R - Right channel output to audio amp
GND - ground
L - Left channel output to audio amp

Connector-2
GND - USB Ground
DP - USB DATA +
DM - USB DATA -
5V - USB 5V

Connector-3 (For SD card connection)
 If you have plan for use only Pen Drive for songs then there are no requirement for Connector-3. You can use your Memory Card using Memory card reader and insert it in USB port.

First you need 5 Volt and 9 Volt Power Supply. Here is complete diagram of IC 7805 5 Volt Power Supply for Usb Mp3 Module Circuit.


If you are using any external Amplifier or Computer Speaker then you can use 5 Volt Mobile charger as power supply for Usb Mp3 module. But be careful when connects charge pins make sure + and – pins have in right way otherwise board may be damage.

The +5 volt power supply is based on the commercial 7805 voltage regulator IC. This IC contains all the circuitry needed to accept any input voltage from 8 to 18 volts and produce a steady +5 volt output, accurate to within 5% (0.25 volt). It also contains current-limiting circuitry and thermal overload protection, so that the IC won't be damaged in case of excessive load current; it will reduce its output voltage instead.
The 1000µf electrolytic capacitor serves as a "reservoir" which maintains a reasonable input voltage to the 7805 throughout the entire cycle of the ac line voltage. The four rectifier diodes keep recharging the reservoir capacitor on alternate half-cycles of the line voltage, and the capacitor is quite capable of sustaining any reasonable load in between charging pulses.
