From the diagram you uploaded I see you are having difficulty designing the circuit. There are a couple things you might try. First, do an internet search for...
Ever, looks like a good circuit. Will the 3031 handle the 220VAC? The data sheet says max 250V peak, and 220VAC has a peak of ^300. Perhaps the 3041 would be a...
If you use 10 bits them use this formula: 5*N/65535. The value from ADc is in 16 bits, but you use only 10 MSB. The uC have register in 8 bits, so for 10 bits...

HI SADIQ, Â HERE I M ATTACHING THE PROTEOUS MODEL AND JPEG IMAGE FOR UR CONCERN TO INTERFACE A TRIAC WITH MICROCONTROLLER.THE CIRCUIT IS TESTED AND WORKING...
hello mazhar are you using compiler win avr ar the other software?? if you using win avr include your adding file  12345.c in M file on the source...
Mazhar, I can see the problem with the code, the big problem is the #include files and where you have put them, Generally try to put the include files in the...
Hi to all the Microcontroller Specilist I would like to have a USB programmer for 89s51 series microcontoller for my laptop Can any one send me the circuit...
Hi all, Â I'm having some no. of pre-programmed IC's, i.e. 89c52x2. Â Now, I don't req. that programs and I want to Re-program it. Â Can anyone can suggest...
Hi all,  Can anyone suggest me the model no. or any detail for hw programmer & soft tool for tht to program 89C52/51X2 controllers?  I'm having some old...
Every condition is true. But in 1st condition,if you put endless loop in isr then no other interrupt routine will be called because ISR disables all inrerrupts...
Nitin, saying that a while(1) loop can be implemented in an ISR is like saying you CAN jump off a building. Of course you can, but would you ? :) ISRs are not...
