Re: Zero Crossing

But in my case what do u think should be the gate resistor value connected from MT2 of BT139 to pin 6 of MOC3021? and how do they calculate its value.

Re: Zero Crossing

Sir i have recoded my program i would like you to go through it and see if it works.I have added a small delay of 2ms right after zero crossing occured and maped my 10k pot to create a delay to the triac gate firing pulse between 1ms to 7ms.Please see if it works now.Thank you once again I LOVE LEAR...

Re: Zero Crossing

No what i had wanted in the first place was to control the time between the zero cross and the firing pulse to the triac gate by the Random Phase Driver, THE Diac (MOC3021) signal from the PIC12F683.The bigest intention was to read the value of the 10k pot one side of it connected to +5v and the oth...

Hi Chipfryer27 i saw your update of my flowchat and its exactly what i wanted now I've learnt how to play around with "MOD" thanks again now am going to build it and see how it goes on a real board next I will need to know how to go about a current meter like from 0-100 or 200A

Re: 3 Digit 7 Segiment quad Display 0-55v Voltimeter

Thanks so much Viktor but to make my understanding this better an example with a 3 digit 7 seg display would be better showing how to display voltages on it instead of an lcd.
