OK cool!! Im taking a look at the triac now. For the solid-state, isn't there a "flyback" diode required?

Hey Master, i tried getting some info on triac's. Maybe you can send me a drawing/schematic using a triac and could you people tell me what's the difference between a solid-state relay and a normal...

Thanks for those quick replies russ n master. Would you happen to know of a specific model 5v relay that would be able to switch an AC load (240v house-hold globe)? I prefer using the relay although...

Hi guys. I want to use my pic to switch on/off a load (240v Light bulb) via a 5v relay. What transistor would be suitable, what relay and what diode should i use for "flyback"?

well i thought by changing the oscillator settings it would sought out th delay but obviously no change. im trying to do some code concerning high led and low led outputs. will post it by the end of...

well, i tested the relay port using a multimeter and there seems to be no voltage output when tempc>=highpt and the same goes for he highled port.

but there was no command prior to this that said goto checkdone. . .

what i meant was that i removed those lines of code. now im using the following which is without the other features i was planning to implement. below is the latest code.


Define LCD_DREG PORTB...

ski, i removed both of those flashing routines and the problem was still there. then i removed the SOUND statements aswel. seemed to have sorted out the lag issue. the problem is that now i have only...

It's for the same reason that I removed those two routines and decided to just make those pins high instead. the same thing happens...

less than half a second.....what r u getting at ski?

hey guys. i just realised that everything is fine until the actual temperature reaches the respective setpoints. thats when the design starts to really slow down during its operation. i cant seem to...

provides debounce for buttons connected to portc

yeah it takes abit longer than before to do stuff. im really concerned as to why this is happening bcause it kinda defeats the purpose of intantaneous measurement. Is there anything you would...

there entire device has slowed down. temperature changes used to be instantaneous. going into the different menu's were instantaneous. for some odd reason every has slowed down.

im using a 4mhz crystal oscillator. I did define it in ADCON0. Bit 6-7 as 11. i would also like to know what difference would there be if i had to amplify the output signal from the LM35. and if i...

BIG PROMLEM!!! After adding on all the extra's (relay code, leds...etc), the pic is operating at snails pace!!! What do i do about this now??

well, the button where connected incorrectly. that being my partners fault. also a few things in the program which where so obvious.. now im gona add in buzzer for high/low and also relays to switch...

just want to apologise for asking too much. i manage to get the thing working. just have to try tweak here and there...

what joy do u get out of being spiteful? all im askin for is guidance..

i've read thru it many times. im no programmer. i'll admit to taking snips from others and to me it makes sense. the main temperature measurement part is mine. the button fuctions is not but i tried...

Does this make any sense? (Well to me it does) At the moment, nothing appears on the LCD. Please could somebody tell me what I need to add/delete to obtain success from this code.

Define LCD_DREG...

myself. Sticking to the basics.

i dont know..this isnt the main concern...lets get back to reality
