I) Rotated Volume Control Key could be connected i) 4/6 Keys On Product ii) Select Forward iii) Select Backward iv) Volume Up v) Volume Down 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. 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. and the capacitor is quite capable of sustaining any reasonable load in between charging pulses. so that the IC won't be damaged in case of excessive load current. .25 volt). It also contains current-limiting circuitry and thermal overload protection. it will reduce its output voltage instead. accurate to within 5% (0. This IC contains all the circuitry needed to accept any input voltage from 8 to 18 volts and produce a steady +5 volt output. The four rectifier diodes keep recharging the reservoir capacitor on alternate half-cycles of the line voltage.Circuit Diagram of 7805 5 Volt Power Supply for 0-9 The +5 volt power supply is based on the commercial 7805 voltage regulator IC. Detail of IR Sensor used in Mp3 Player for Remote Control Full Name – IR Sensor Receiver with Metal case Note:-Please use same Sensor with Metal case for Mp3 player.3 Volt from Usb mp3 player module or circuit. Use 1st pin as IR or RI Signal . Notes. Use 2nd pin as GND(-). 3rd pin to 3. . I publish these buttons connection only for knowledge view. Use Both L and G (Gnd) if you are using outside Audio system Like computer Speaker or any Amplifier device. Computer speakers pin have three points so you can use all three points (L. G and R).In picture you can see starting pins ( L G R).Complete Connection Diagram of Usb Mp3 Player Circuit Module with all Pin Details Here you can see TackTileButtons connection in picture if you are using Remote control only then there are no need any connection for buttons because all control like volume up down Next Previous control with Remote easily. Ground and Right Audio. See Picture . Note:. If you have plan for use same power supply in both Audio Board and This mp3 player circuit then don’t connect pin G (Ground) to any point otherwise output sound may be not clear. These pins are for Left Audio. Speaker can be a 4 ohms one. low distortion.6 watt 9 to 12 Volt Audio Amplifier circuit diagram for Mp3 player using TA7222A IC Here is complete easy to understand amplifier circuit for create external audio amplifier with good quality sounds. More Description: Here is the circuit diagram of a 6W amplifier using the TA7222AP from Toshiba. high ripple rejection. This amplifier can be operated from 9 to 12V and this makes it ideal for car radio mp3 playersapplications. Notes. The IC must be heatsinked. The IC has very good features like. short circuit protection. muting function. For optimum performance input and output must be separately grounded.8W to a 4 Ohms load at 12V supply voltage.TA7222AP is an excellent integrated audio amplifier which can deliver 5. You can use Mp3 player Module circuit audio output as input in this circuit. . The circuit can be assembled on a Vero board. Use 12V DC for powering the circuit. thermal shut down etc. 25" This circuit is a compact design AF amplifier based on the TBA810 Integrated Circuit. the circuit has low/high impedance inputs which can be connected to any audio source.75" x 2.
