I will use a transformator to convert voltage to 6V 1A, and i will use a L7805C-V to regulate power for the microcontroller and sensor (and that makes a Vcc for me). Is it safe to connect the output of the regulator directly to the microcontroller and sensor? I've added some resistors to limit...
I've seen that...
The truth is i already know how to handle the frequency, it is using the S0 and S1 pins on the sensor (and if that can not be done, we can always reduce the counting period:rolleyes: ). You can obtain the datasheets of TCS230 (i've downloaded em all) at http://taosinc.com...
It's got to be hard to see.
:yuck: i reviewed my post and i found out that it will make your head spin to see the image. so i repost the figure.
and since the picture is not so detailed, i want to note that the red arrowheads on board3 is meant to be diodes.
Greetings,
Currently, I'm designing a project to sort objects using AT89C52 as the "brain" and TCS230 as the "eye". And so, it is necessary for me to connect the AT89C52 with the TCS230 colour sensor and stepper motors. And before doing the real thing, i must know the frequency range of the...
thanks for the answer. It is obvious, but it is just my first time using microcontrollers. i will try this right away.
thanks again.
Oh.. and one more thing. like i said before. can i use a port as an input and an output simultaneously? my mistake to mention timer 2 on port2. it is timer0 and...
I'm doing a project of sorting objects, and this is the first time I'm working with microcontrollers. I am using AT89C52 microcontrollers. i just couldn't understand these statements in the datasheets.
"When 1s are written to Port 2 pins they are pulled high by the internal pullups and can be...
I don't understand entropy very much:confused: , but i believe it's similar to shaking a bottle with water and oil in it. The water and the oil will mix temporarily. After a short period, the water will go down and the oil will go up. I've read nothing about its explanation, but i suspect...
could you explain "burning particulates" better? is it shining particles? particles emitting hot lights(energy waves)?
that would be heat i think. it is the same thing when LUP focused light burns papers.
I think of flames as groups of excited particles. The cause of excitation could be...
Looks like everyone is agitated.
I'm sorry that i couldn't be much of a help. I'm still a college student after all. I believe that Mr.Glen would be happy to see your theories so that he could build a comprehendable experiment.
I suggest asking Mr.Glen directly via email about the detailed...
Sorry to add up oil in the fire.
One more fact that i know is that the coke can also gets colder when you shake it. Try an unfrozen can of soda.
It comes to me that the shaking could probably do something like when we are stirring a spoon when we are mixing coffe with milk or sugar. I presume...
When i was learning electronic stuff on the site, i found this... perhaps somebody could help the webmaster.

i've got no idea.
Thanks Danger
Thanks... sure i will.:biggrin:
Chinese proverb says "It's easier to stop the river flow from the streams" means "It's easier to handle problem when it still a small problem" or something like that. I just don't want we to have a massive problem like "green house effect" arise...
i don't know about that, and i couldn't try installing grid wires on those wind turbines because I'm faraway from them (about half of the Earth circular length :rolleyes: ).
I did and do hope some virtuous scientists would work on this. My location and my education do not permit me to help...
I don't know much about the real thing... but... when i think about it..., not blocking the wind, but blocking the birds... how about a gridlines (perhaps from metal wires) sorrounding the wind turbine? (added cost of course)
If this solution to be taken, then make sure the grids make a...
ehm... when i say theta, i mean
"the angle between the horizontal line along the peg and the point where the ball starting to leave the circular path.
and also, i was assuming that the peg was "straight" below the supporting point
i'm on it
agree
somehow i couldn't agree. i imagined the ball stopped vertically at one point above the peg. and that makes the velocity components (vy=0, vx= something). and from that, i worked out that
d=100 - {(2*vx^2*sin(theta))/([cos(theta)]^2*g)}
i'm working the vx. I'm trying to...
Thanks for the information...
i've checked the site... i really don't mind the adds.. the contents there are very helpful. and it looks like i can find almost everything here.
thanks again.

hello... I'am Fandi from Indonesia.
Because the lack of books and the economy crisis present in Indonesia, I encountered problem in finding good reference.
can anybody tell me how generators supply electricity to houses? is there any online references?
Thanks before. :smile:
i need to think about it since i was looking for an operation of 3D angles. when i got a vector which is stated in spheric coordinates, suppose i the vector components are r1, phi1 and theta1. how can i find the angle between the vector and the x axis... but i think i know the answer now. I...
need a "basic" help
this may be a silly question... but, i really need this, because a basic is the stairway to the advanced of course.
i thought that this forum may provide more help than i could get in my college.
please tell me...
how do we find an answer of "sin(theta)" without an...
seems that I'm just too late to get in the discussion, but since i really wish to post my opinion... well... you know .
When the car hydroplanes, i think, it will got such resistance that the speed decreases, and the acceleration either. It would be somewhat like a beam is biassed from air...
Hello hello... I'm a newbie here... see me pleaseee
may be I'm just not the right person to quote about these materials. (my modern physics score was "C")
well... one argument about that..., what WE exactly measured was the flash of light which according to the famous Maxwell (i believe)...
