when you give clock and data to the shift registers
it stores data in its entire circuit but do not save it till you no give it latch (ST_CP) signal .
latch also called strobe signal.
next thing OE.
OE means output enable .
you can use this pin to enable output and disable output.
in your...
shift registers can only display one row at a time .
so you should display all the rows first for a while and then shift every row one step and
scan display again.
while shifting data to cascade shift registers it is not displayed on led's till you give latch pulse to shift registers.
so...
Thanks for your reply.
i was using this driver **broken link removed**
i am wonder .
even i have connected full bridge across motor , rc filter , isolation and
no effect.
after connecting this Amulet (filter ) everything is working fine.
HELLO GURUS.
recently i have faced a problem about high noise of a high speed dc motor.
.
I was trying to implement pid controller using arduino, with 500hz pwm frequency.
Arduino -->> optocoupler-->>l298 (motor driver)-->>motor-->> cutt sensor(for rps) -->> Arduino (feedback).
rps=...
you need a zero crossing circuit like this.
**broken link removed**
it will give your controller a signal at every zero value of your sine wave.
then you need to program your controller for firing of thyristor.
zero crossing will raise after every 10ms. Its mean you have 10ms time between two...
DEAR sir Tahmid.
as maximum value of adc is 1023 .
so if we want to obtain 5000 value at 5 volt
we should use this formula.
AdcValue= AdcValue*5000/1023;
here is a link your personal artical https://www.edaboard.com/blog/1569/
dear milan.rajik .
you can order any transformer maker to...
You are right MR swapan .
i have worked for 5 years in stabilizer field.
there are 2 major reasons to ignore your great idea.
1:> stabilizer is very cheep item, it should be as cheep as possible.
2:> stabilizer is mostly used in rural areas . there are not available trained engineers.
So...
i have tested and it is working properly .
read the circuit diagram (specially relay connections ) carefully given in post #9 to understand programming.
stabilizer circuit works like a selector switch.
which select transformer taping from transformer to maintain output voltage.
i have designed this selector switch in programming.
which reads output voltages and change selector switch position according to required output.
