Great work! Worth a read! yes

Very good
Plg upload for voltage analayser for us

plg upload for 12v  battery charing circuit wit  lowand high  voltage cut off  funtions

 

 

Hello,
Nice article indeed
But There is a bit correction in the theory and eventually in the program.
When you touch the wheel to a rotating body then they will have same RPM only if their radius is same.
Remember HSC physics:
But mostly you will touch it to a rotating body which has larger radius, hence that rotating body will have less rpm but your wheel will rotate at higher rpm.
you have to include the formula for correction.
I don't remember what is it, but its something like:
V=rv/R
R= radius of rotating body
V= angular velocity of rotating body
r= radius of the wheel

v= ang. vel. of wheel

very good gadget. Only wish if could show some mathematical parts,especially for the choice of components.thanx

anybody suggest a codings  for  tachometer in pic16f877a microcontroller.

 

thank you

where coding this program crying

please reupdate code this project crying

Please give source code.

Hi Very Nice. Please send me the source code. Thanks.

Where are source codes?

so good

Great work!

very good
