i am making a flame sensor so want to filter all the other frequencies and only leave the candle flame frequency.thanx in advance

can any1 tel me the actual frequencies produced by a burning candle

can any1 send me the schematics on how to connect xbee modules to pic18f452 without adpters.is it necessary to connect level converters

i have connected the sensor as per the picture above.i left the sensor to stabilize for about 10minutes and then checked the output voltage it was 56mV and then blew into the sensor.the output voltage dropped to about 47mV which is something i expected. i blew two more times and the output voltage s...

i have followed the link you provided, http://www.picbasic.co.uk/forum/showthread.php?t=8709 and now i do not understand how the H pins are connected, are we supposed to shot them and then connect them to 6V??
thank you in advance

i recently purchased a carbon dioxide sensor ,MG811 but then i donot know how to test it.may you please help me on how best i can test the sensor without damaging it.i need to kno how to identify pins A and B. its not really clear in the data sheet

thank you in advance

for now i managed to reduce the code considerably and the stack overflow error has disappeared

good people anyone to rescue i am getting stack overflow error as i simulate my code on proteus. i just do not know wat to do pliz help me what usually causes stack to overflow

hi everyone today i wanna ask if the message numbers that appear when compiling a code mean anything.if they do can someone pliz help me understand what the message numbers mean. this can help me quickly correct errors should the code have some by just referring to the error message numbers

i need help on how to register the mikroC compiler.i am writing a code and upon compiling i am getting a notification that i have exceeded the demo limit.pliz help fast because my project is due in 3 weeks and i need it done as soon as possible

well thanx bt i got it working by connecting positive supply to pin 16 and ground to pin 15 which is the opposite to what the datasheet says

its now displaying my text but now the back light is still off

hello there i have connected an LCD to pic18f4550 mcu's portd.i have left D0 to D3 floating and my lcd has failed even to show the smallest light.any1 to help me.any problem leaving those data lines floating?

actually it could detect that a target circuit was connected but then the IDs didnot match even after several times of setting PIC18F452 in the configuration bits.
