hello
Can somebody pliz tel me the advantages of using the method of integral cycle method of heat control over any other methods that can b used.
YO help is greatly appreciated!!!!!
thanx
hie
I wld want to use RB0 to count the rising edges from a zero crossing detector. i will then count the number of pulsese.g 200 pulses.
pliz help me wit the code if someone has it
thanx
hie
how could i calibrate an A/D pin of pic 16f872 to measuer temperature without amplifyint the output from the sensor
If anyone has .asm code pliz help
integral cycle control
hie thanx ravimarcus for the code for the lm35adc. i wil try it out and c if it works out.
If there is one who knows mo about the principle of integral cycle control help. I would like to use it tro control heater temperature. If u could really help me with the code...
using lm35 on pic 16f872
hello
nid some. I am usin a sensor lm35 to measure temperature and feeding this to a pic 16f872 thru RA0 which is an A/D port. Is it ok if i directly input the voltage from the sensor to the pic. The voltage is in mV e.g a temperature of 26 degrees gives a voltage of...
Greetings
Im kindly and desperately looking for a code to count the pulses from a square wave using a pic 16f872. i want these pulses to be the basis of varying the turn on time of a heater connected to the pic and switcing being done by a triac driver and triac.
zero crossing detector comparator
Hello
Im looking for a working circuit for a zero crossing detector employing a 741 op amp. If possible a zero crossing detector which can produce pulses at only the positive or negative-going zero crossings.
Hie
I am looking for a circuit employing a 741 op amp or LM358 which can be used used as an amplifier with a gain of 5, amplifying a voltage of 1V to 5V.

how to convert voltage to degree celcius
Hie
Lookin for a code to convert the voltage output from the LM35 temperature sensorn being fed into a pic16f872 to degrees celcius and displaying the measured temperature onto an hd44780 lcd
hie
Im looking for a full working code for a pic16f872 which accepts an input from a temperature sensor(LM35) compares it with a set temperature and varies the duty cycle of pulses from a zero crossing detector which also feeds its output to the pic.
The measured temperature from the pic also...
how to use pic16f872
May someone pliz help me with a code for setting a certain temperature and comparing it with a temperature from a sensor connected to a pic 16f872
I am building a pic based heat controller which switches at the zero crossing points of the a.c mains. I have an mc3041 triac driver with an inbuilt zero cross detector, so is it neccessary for me to use a seperate external zero crossing detector.
