Well that made this a WHOLE LOT easier!  Thanks.

Ethernet shield w/POE -- Can it run with normal power hookup?

Posted: 16 Jun 2013 04:54 PM PDT

Hi, I am building a project at home that will eventually be installed in a location with limited access to power.  I do not have a PoE switch at home but this will be installed where there is PoE available.. My question is this: Can I use the Ethernet ...

The delay goes immediately after:
Code:
ds.write(0x44,1);

Yes I do, I connect my arduino directly to my computer LAN Port with LAN cable....
do I put the right IP configuration ? or I missed something here ?

Disable USB power so when connected via USB without Ext power, Arduino is off

Hi,

I'm building a little control project that communicates with a PC via USB but uses (and needs) an external power supply to function, however I only want the board to be powered from the external supply - never from USB. If only USB is connected, I ...

I am just putting together a list of parts and need a good source for the Wal Wart.. Does it have to be 3.3V or can it be higher???  What is the plug style? and is it center pin positive?

I tried adding a delay(750); right before ds.write(0xBE); //Read scratchpad, but it didn't work. It still is showing up as -1000. I don't think that the sensor is being recognized.

mr_johansen, is this the USB-to-Serial adapter you're using?
Well as he said it had a 9 pin serial connector then I don't think so.

Re: Calculator with serial communication problem.

Posted: 16 Jun 2013 03:11 PM PDT

Wow thank you! thats really cool!

But is their a way to just send the problem to the arduino?

example = 3+3

then it should reply with 6.

Can it just take the string I send it, and compute?

To be honest, I am also new at programing c++. But I did in-f...

Look carefully at the Arduino examples.  Notice how most statements (not every line) end with a semicolon?

I've been using PWM more often than Input capture.

Since there isn't an appreciable difference between the boards to cause the problems you are describing, maybe there is a non-obivous application issue causing the "problem".

I think it would be good to post the schematic of what you have wired.  Again...
