    Is it really …
    Is it really pronounced? Ardoo wee no? I’ve always said it was Ardweeno. Not that it matters really, just curious if there was an official way to say it.

    Hey Jeremy,

    Thanks a lot for all of your videos, they have been really helpful! I have 2 questions:

    1. Can I use this method of communication to talk? to another Arduino?

    2. If so, how do I attain the address of the Arduino I would like to use as the slave?

    Thanks again for all your tutorials man!

    Cheers,

    Greg

    @obeliskdix if you …
    @obeliskdix if you want to go all out, you could get an ethernet shield for the arduino and make it put the value on a website, then write an app to fetch that data. App could be written in Google App Inventor(although they might have already shut it down by the time you read? this)

    Jeremy could you make a video like this but the vid you’ll be making is how to display the temperature on android tablet screen or any android phone.? . . If there are others here who knows how to do it please share it, show it or send me infos about it to my mail sadex_17@yahoo.com. Thanks to all. . .

    What kind of input will 16 byte digital I2C communicated 3 axis gyro give?
    And how could? I show the input as degrees?

    @sciguy14 Did you have to click on the serial monitor first to cause the arduino to go into the ‘transmit state’ ? If I unplugged my arduino, I would have? to keep on opening the serial monitor otherwise the degree and Fahrenheit would not show up in processing.

    @1ofakindwork You’ll need either an? extrnal RTC chip, or you’ll need to have the arduino hooked up to the web to use accurate timing like that.

    Thanks Sciguy,

    Thanks Sciguy,
    I’m having a hard time finding the information to see if the arduino will work for my idea. Can you point me in the direction of some solid information on the RTC and? it’s applications. I haven’t seen anyone use the RTC for controlling multiple dc motor at set time and intervals.
    I want to run a dc motor for 1 min at 7am, then run it at 9pm with the polarity reversed.
    I’m also unsure of how much multitasking the arduino can handle.
    1 RTC
    1 dc mortor
    2 servos
    1 sound board

    @sciguy14 Thanks! I realised that my connection to pins 2 and 4 had to go to 20 and 21 because i have an? arduino Mega 🙂

    @CIPHERJAY Look at the codes table on page 13 for TO-220 package. 1001000 =72 for the A0 device. Is yours A0? It might be something else, in? which case you should use that address.
