THERE IS DIFFERENT TECHNIQUE FOR DRIVING GLCD
THIS CODE WILL NOT WORK
SEARCH ON THE INTERNET LOT'S OF DETAILS THERE
i have build a project of "Telephone Supervisor" published in dec-2005
it working perfectly and fine ..
but i am facing only one problem is that the ringing is not detected by it..
i think there is something standered problem ( AS I AM FROM INDIA) or not sufficient ringning voltage at...

HI TO ALL
I AM MAKING A PROJECT USING S202S11
IT IS A Solid State Relays Built-in snubber circuit
Non-Zero Cross type.
BUT I AM UNABLE TO FIND IT LOCAL MARKET
SO COULD U PLEAS THE EQUVALENT CIRCUT FOR IT SINCE I THINK IT CAN POSSIBLE BY USING A OPTOCOUPLER(MOC3011) AND A...
hi
i have make a project of 10 channel infrared control using pic 16f84 published on silicon chip
and the problem is that accourding to the article it use rc5 code with sat1 and sat2
so i first i am facing problem to find right remote for it
and please guide to understand the difference in rc5...

I have just completed my new project..
It is very interesting “ 8 channel switching via power line”
It works on the principle of DTMF tones
The project is completed
The output tone is mixed with neutral and the ground with earth
...
YES
THE OUTPUT VOLTAGE OF PARALLEL PORT IS ABOUT 4.2 V
I HAVE USED 78L05 AND 78L08 WITH 15-0-15 TRANFARMER
THE SUPPLY ACROSS7405 IS ECACT 5 VOLT AND THE VPP IS ALSO EXACT 13 VOLT
UES THE VALURE OF RESISTORS ARE OK
THE 100 NF CAP IS ALREADY CONNTECTED TO ACROSS THE OUTPUT OF 78L05 AND SAME IS...
HI TO ALL
I THINK THERE ARE MAJOR PROBLEM OF WRONG BILLING OF ELECTRICITY
AND ALSO THE MORE ENERGY CONSUMPTION THEN RATED POWER BY APPLICES
SO I WANT TO DESIGN A ENERGY METER FOR SHOWING WATT CONSUMPTION
AND IT SI GOOD IF IT CAN SHOW VOLT AND CURRENT
BUT I AM GETTING PROBLEM TO DESIGN CURRENT...
THANKS FOR REPLY
I DID IT THE SAME AS U MENTIONED AND Delay_VDD_ON VALUE IS ALREADY 3
BUT STILL IT SHOWING HARDWARE FAULT
I CHECK THE 7405 VOLTAGE THERE IS SOME STRANGE OUTPUT
VDDD AND VPP ARE WORKING FINE BUT ON
CLOCK AND DATAOUT PIN
1) WHEN DATAOUT IS SET 1 THE CLOCK PIN IS WOKING MEAND...
