triac speed control circuit
Hi all,
Thanks for ur suggessions. Let me try all these methods suggested by u and study of PDF documents suggested by sinsina is also essential. I ll make my feedback ASAP

fan speed control using triac
Hi Ave_Rapina
Thanks for ur post
I am already using a circuit using BT136D and i cannot change it. So using MOC is not practical for me and also using IGBTs is also not good for me. Then using PWM is OK but how???
I am using the same circuit for a...
triac fan speed
Hi all,
How to control speed of a fan (230V) using logic level sensitive triac BT136D with a PIC uC (16F72).
Well familiar with PIC
Using CCS Compiler
Just Ideas are enough (Coding is not an issue)
Thanks in advance
Gladis
Re: What precautions should be taken when programinning I/O
Hi,
One thing u hav to make clear is that: What is the thing u r connecting to the I/O. Are u trying to connect LEDs to I/O pins ?
If u r connecting an LED in I/O pin then u hav to simply use a series resistor of 470E and connect...
Re: problem with 7805
Hi, Problem ia absolutly not with 7805, may be with ur code. Put a small delay for power-up approx:100ms at the beginning of the code. Which transformer are u using?
Re: Problems...
Hi,
when u r adding offset to PCL, the content of PCLATH is automatically loaded to the higher byte of PC. So before adding offset to PCL load PCLATH with higher byte of your offset.
For Example: If your u want to go to address 0x1000, and if ur current address(PC value) is...
Hi,
1. Select required prescaler and load T1CON with ur configuration required
2. Set TMR1CS bit in T1CON for selecting External clock, this to configure TIMER1 as counter
3. Clear TMR1H and TMR1L registers
4. Set TMR1ON bit to start counting
5. To stop counting, clear TMR1ON bit. Timer will not...
Hi,
16F914 is good enough to do ur project. Hav u completed ur circuit design?
Otherwise u hav to select a DAC for ur application. When selecting a DAC u hav to look for these parameters
1. Interface: Parallel or serial (If u r slecting Serial DAC then u hav to choose SPI or I2C interface...
Hi,
24FC1025 is simpply a 1Mbit Memory chip used for small memory applications, the advantage is that this part supports high speed I2C bus - Speed upto 1MHz.
Re: LDR 16F877
Hi,
For ur application 16F877A is more suitable than 16F877 because it has in-built Comparator Module. From Comparator u will get a 0 or 1 and also it has internal voltage reference so that u can set ur voltage as required.
In 16F877
Connect LDR to any analog channels and...
Re: source code help!!
Hi
A=256*B+C
For this u hav to write a sub routine for multiplication. This can be done using successive addition. If ur value 256 is fixed then u need not want to multiply it. Simply put two zeros in right side.
For example: if B=0x23, then 256*B will be 0x2300, that...
