    Will this circuit work?

    thanks.... that solved it. I will work it right away.:biggrin:

    Will this circuit work?

    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...

    Will this circuit work?

    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...

    Will this circuit work?

    It's gotta 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.

    Will this circuit work?

    Greetings, Currently, I'm designing a project to sort objects using AT89C52 as the "brain" and TCS230 as the "eye". And so, it is neccessary 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...

    okay... thanks

    Help me with I/O Please

    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...

    Basic electricity

    looks like that would be a long long journey to go. god speed.

    Help me with I/O Please

    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...

    Pressure in soda can

    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...

    What flames made of

    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...

    About Lightning

    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...

    Pressure in soda can

    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...

    About Lightning

    When i was learning electronic stuff on the site, i found this... perhaps somebody could help the webmaster. http://www.williamson-labs.com/lightning-motion.htm i've got no idea.

    How to avoid killing birds with wind turbines

    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...
