    خلينا نتشارك افكار مع بعضنا في مشاريع التخرج

    مرحبا اخواني ما بعرف اذا هذا الموضوع متكرر لكن لفت نظري انا في شباب كانت تتعب في ايجاد فكرة المشروع اكثر من تطبيقه فحبيت انه نتشارك الافكار علشان نمهد الطريق لعمل المشاريع لا لشرائها جاهزة وبارك الله فيكم...............

    دعوة من اخوكم فلسطين والنضال

    Voice recorder using ADC and microcontroller

    voice recorder using ADC and microcontroller.Create a voice recorder using a
    PIC or a microcontroller and ADC. Use some conditioning circuits to condition the microphone output and feed it to the ADC. The converted values can be stored in some kind of memory. Samsung has got some nice memory chips that can be easily interfaced. Most modern MP3 players use this kind of memory. Use a DAC to convert the stored voice data back to analog format and play it through a speaker. If you feel that this is very simple for you then interface a keyboard and LCD display and make it look like a real voice recorder. Give options to change the storage format, like bit rate, frequency etc. Still you are not satisfied…… then use an ARM processor to implement this. Convert the voice to MP3 in real time and store the Mp3 data. Also write code to play back the stored Mp3.

    GSM CONTROLLED DOOR LATCH OPENER WITH SECURITY AUTODIAL-UP



    THE SAID PROJECT IS DESIGNED ON THE DTMF DECODING.OUR MODERN TELEPHONE AND EVEN OUR MOBILE PHONE USES DTMF CODING FOR NUMBER DIALING. THESE DTMF CODES CAN BE DECODED AND UTILISED FOR USEFUL PURPOSES. THE CIRCUIT UTILISES IC8870 FOR DTMF DECODING . MICROCONTROLLER 89C51 READS THESE CODES AND TAKES THE NECESSARY ACTION. DOOR LATCH CAN BE OPENED BY ENTERING THE CORRECT PASSWORD , YOU CAN ALSO CONNECT SECURITY SENSORS OF YOUR CHOICE ,IN CASE OF ANY BREACH OF SECURITY TAKES PLACE , THE DEVICE WILL DIAL OUT THE PRESTORED NUMBER AND DELIVERS AN EMERGENCY MESSAGE.
    CIRCUIT DESCRIPTION: TELEPHONE LINE IS CONNECTED AT CONNECTOR K1. WHENEVER SOMEONE CALLS THIS NUMBER, THAT TIME TELEPHONE LINE CARRIES ABOUT 70V RINGING SIGNAL SIGNAL IS RECTIFIED BY THE BRIDGE D5-D8 AND FILTERED BY C4, R20, AND D9 AND DRIVES AN OPTO COUPLER IC U8 MCT2E . COLLECTOR OF THE OPTOCOUPLER WILL GO LOW WHENEVER BELL RINGS. SINCE THE COLLECTOR IS CONNECTED TO P2.7 OF MICROCONTROLLER 89C51. NUMBER OF TIMES IT GOES LOW IS COUNTED BY MICROCONTROLLER. AFTER SIX TO EIGHT RINGS,P1.0 WILL GO HIGH AND SWITCH ON TRANSISTER T4 AND ENERGISE THE OFF HOOK RELAY RL1 . THE CONTECTS OF RELAY RL 1 WILL BECOME CLOSED AND THE TELEPHONE LINE WILL GET CONNECTED TO DTMF DECODER IC 8870, THROUGH C7 AND C8. RESISTANCE R8 COMES ACROSS THE TELEPHONE LINE AND THAT LOWERS THE VOLTAGE,AND THIS ULTIMATELY SENDS MESSAGES TO EXCHANGE THE USER HAS LIFTED THE HAND SET. AT THE SAME TIME ,MICROCONTROLLER PIN P3.5 WILL TRIGGER THE VOICE IC API8208 WHERE ALL THE MESSAGES ARE STORED. CALLER WILL GET THE MESSAGE”PLEASE INTER THE PASSWARD”THE DEFAULT PASSWORD IS 1-2-3-4-5-6. WHEN CALLER ENTERS THIS 6 DIGIT PASSWORD. IC 8870 DECODES THESE NUMBERS AND BINARY NUMEBRS ARE AVAILABLE AT Q1 TO Q4 ,PIN NO 11-14 OF DTMF DECODER WHENEVER NEW CODE COMES PIN NO 15( STB) OF DTMF DECODER WILL PULSE LOW, AND IS CONNECTED TO P1.1 INFORMING MICROCONTROLLER THAT CODES ARE AVAILABLE PLEASE TAKE THEM . MICROCONTROLLER WILL READS THESE CODES ONE BY ONE, THROUGH ITS LINE P1.2-P1.5. IF THE CODES MATCHES WITH THE CODES INSIDE THE MICROCONTROLLER, MICROCONTROLLER WILL SWITCH ON THE ELECTRO MAGNETIC OPERATED LATCH FOR 10 SECONDS AND USER CAN ENTER THE APARTMENT . IF THE PASSWARD ENTERED IS NOT CORRECT. MICROCONTROLLER WILL DISCONNECT THE TELEPHONE LINE WITHOUT ANY REPLY, BY MAKING P1.0 LOW.
    1. IF THE PASSWORD ENTERED IS CORRECT. YOU CAN ALSO CHANGE THE PASSWORD STORED. THIS PASSWORD STORED GOES INTO SERIAL EPROM IC 9346 THAT IS NON VOLATILE RAM IN CASE POWER FAILS THE PASSWORD IS NOT LOST
    IF YOU WANT TO CHANGE THE PASSWORD FOLLOW THESE STEPS
    DIAL THIS NUMBER FROM OTHER LINE AFTER SIX TO EIGHT BELLS YOU WILL RECEIVE MESSAGE ” PLEASE ENTER YOUR PASSWORD”. (1,2,3,4,5,6 and #)SO YOU ENTER YOUR PASSWORD AND WAIT FOR THE MESSAGE IF YOU ENTER 2 THEN DEVICE WILL RESPOND PLEASE ENTER NEW PASSWORD WHEN YOUR PASSWORD ENTRY IS OVER PRESS # AFTER PASSOWRD ENTRY INDICATE THAT YOUR ENTRY IS OVER AND MICROCONTROLLER WILL RESPOND “YOUR PASSWORD HAS BEEN CHANGED’’ KEEP THE HENDSET BACK ON THE INSTRUMENT FROM WHERE YOU ARE CALLING.NEXT TIME WHEN YOU DIAL ,YOU WILL HAVE TO ENTER YOUR NEW PASSWORD.
    SIMILARLY YOU CAN ALSO CHANGE THE TELEPHONE NUMBER.
    IC U7 4047 ACTS LIKE WATCHDOG AS LONG COMMUNICATION IS GOING ON IT DOES NOTHING THE MOVEMENT COMMUNICATION IS OVER ITS OUT PUT AT PIN NO 10 CONNECTED TO PIN P3.2-INT0 WILL INTERRUPT THE PROCESSOR AND PROCESSOR WILL MAKE THE P1.0 LOW AND DISCONNECTING TELEPHONE LINE .THE TIME TO SWITCH OFF THE OFF- HOOK RELAY IS DECIDED BY C6 AND R19 CONNECTED TO IC 4047.TRANSISTER T1 AND T2 DRIVES THE LED D12 TO GIVE VISUAL INDICATION OF COMMUNICATION. TRANSFORMER TR1 IS 1:1 TRANSFORMER (160 OHM) PROVIDES ISOLATION BETWEEN TELEPHONE LINE AND SPEECH CIRCUIT.

    This Dummy Alarm project makes an LED flash briefly once every 5 seconds to imitate the indicator light of a real alarm. The circuit is designed to use very little current to prolong battery life so that it can be left on permanently. An on/off switch is not included, but could be added if you wish.
    The 7555 timer IC used is a low power version of the standard 555 timer. A 'superbright' red LED is used because this provides a bright flash with a low current. The LED is off for most of the time so the average total current for the circuit is less than 0.2mA. With this very low current a set of 3 alkaline AA cells should last for several months, maybe as long as a year. The circuit will work with a standard 555 timer IC (such as the popular NE555) but this will increase the average current to about 2mA and the battery life will be much shorter. You can use a greater supply voltage (15V maximum) for this circuit but the 1k resistor for the LED should be increased to keep the LED current low at about 3mA. For example to use a 9V PP3 battery change the 1k resistor to 3k3. Note that AA cells will last longer than a 9V PP3 battery.

    MCU: PIC18F2550 with external xtal,
    ADC: one channel 0-2.5V sigma-delta converter, Linear Technology LTC2400/LTC2420,
    6-channal 10-bit ADC 0-5V,
    Display: Two connectors for text LCD or GLCD,
    USB: onchip USB port with type B connector,
    Power supply: onboard low dropout regulator, rechargeable battery,
    Code programming: 10-pin header for In Circuit Loader.

    The board platform is suitable for developing the microcontroller based instrumentation. Students may build the signal conditioning board, plugs it to PIC project board, develops the code and programs it with
    loader cable easily.

    Figure 1. PIC18F2550 Project Board (click to enlarge)Figure 2. Text LCD displays analog input.

    Hardware

    The MCU is 28-pin PIC18F2550 with external xtal as the option. We can use internal oscillator. The loader uses only three pins, PGD, PGC and MCLR. J1 is ICSP header, we can plug it to the application board for both code loading and running. The user I/O ports is 6-channel analog input RA0-RA5. PORTB, RB0-RB7 is for LCD interface. User can choose either text LCD at JR1 connector or GLCD at JF1 connector. PORTC, RC0-RC2 is used to interface the LTC2400/LTC2420 SPI bus, sigma delta converter. RC4 and RC5 is USB port signal. RC6 is also available at J2. RC7 is debug LED. J1 is ICSP header. D2 protects VCC from high voltage programming at MCLR pin. U2 can be 20-bit or 24-bit resolution, sigma-delta converter, LTC2420 or LTC2400. J3 is jumper for selecting rejection of the common mode noise frequency, 50Hz or 60Hz. The reference voltage, +2.5V is generated by U3 LM336. The board can be powered by rechargeable battery, BT1.

    Sample Code: Interfacing LTC2400

    The sample c program shown in Figure 8 demonstrates interfacing to sigma-delta converter, LTC2400. The MCU uses 4MHz Xtal with HS oscillator, no division option. The program reads 24-bit data from LTC2400, performs digital filtering and displays input voltage in 0.1uV unit.
