			<description><![CDATA[Hi,<br />Does anyone know of the whereabouts of a solar AA NiMH rechargeable battery charger kit?<br />They seem to be more powerful than Lipoly batteries and there is a handy case for 2 xAA batteries with the Minty boost kit.  A solar charger circuit for the batteries would be useful but is proving difficult to find.<br />Many thanks.]]></description>

			<description><![CDATA[jedihonor -<br /><br />You can't connect two TC74A1's to the same bus, because they have the same I2C address.   The suffix of the part number tells you the address: TC74Ax, where x=0..7. As jedihonor points out, you would need two different part numbers to do what you're trying to do.]]></description>

			<title>Re: How to Connect Multiple MCP23017s</title>
			<description><![CDATA[One way you could do it would be to declare an array of Adafruit_MCP23017 objects. Then, write an intermediate function that you call instead of mcp.digitalWrite(output, HIGH);<br /><br />In the intermediate function, you can shift the output number right by 4 bits (i.e., divide by 16). That will give you the index to your array. Then you can perform a logical AND of the output with 0x0F to give you the local output address for the selected string.<br /><br />So, your call to digitalWrite would look something like this:<br /><dl class="codebox"><dt>Code: <a href="#" onclick="selectCode(this); return false;">Select all</a></dt><dd><code>mcpArray&#91;output&gt;&gt;4&#93;.digitalWrite((output &amp; 0x0F), HIGH);</code></dd></dl>]]></description>

			<title>MEga 2560 + Ethernet Shield + Motor Shield</title>
			<description><![CDATA[I am having problems with the Arduino crashing when after receiving a few inputs. It only happens with the motors attached and I am wondering if it is due to incompatibility between the shields.<br /><br />&quot;The following pins are in use only if the DC/Stepper noted is in use:<br />Digital pin 11: DC Motor #1 / Stepper #1 (activation/speed control)<br />Digital pin 3: DC Motor #2 / Stepper #1 (activation/speed control)<br />Digital pin 5: DC Motor #3 / Stepper #2 (activation/speed control)<br />Digital pin 6: DC Motor #4 / Stepper #2 (activation/speed control)&quot;<br /><br />&quot;Arduino uses digital pins 10, 11, 12, and 13 (SPI) to communicate with the W5100 on the ethernet shield. These pins cannot be used for general i/o.&quot;<br /><br />Since they both use pin 11 this would cause a problem right?<br /><br />Thank you for thoughts/inputs.<br /><br />-Simon]]></description>

			<title>Re: Chronodot and LoL Shield conflict   HELP!</title>
			<description><![CDATA[Good point, Stephanie. The LOLShield library does use quite a bit of RAM.  But that should all be statically allocated whether he calls LedSign_Init() or not. I didn't spot any mallocs in Charlieplexing.cpp<br /><br />According to GoolGaul:<blockquote class="uncited"><div>In the sketch shown, all the Serial Monitor shows it &quot;20&quot;...</div></blockquote><br />So that means that it didn't actually hang in LedSign_Init() - it got past that and hung up someplace early in loop(), after he prints the Century.  My guess is that it actually hangs in Clock.getYear(), which is the first place he actually calls the DS3231 library (that's why I was wondering what library he's using - the DS3231 library I found on GitHub doesn't have a getYear() member).<br /><br />If this RTC library is doing malloc's when getYear is called, then it's entirely possible that the system could be running out of RAM.]]></description>

			<title>Re: Scaling a 0-15V analog signal for max resolution</title>
			<description><![CDATA[<blockquote><div><cite>philba wrote:</cite>Also, you wanted better resolution in the voltage range that you cared about, 9-15V.  Given the title of your post, I assumed it was the most important thing to you.  That is what the differential op amp config will do.</div></blockquote><br /><br />Thanks for your comment Philba.. I will do a test with OpAmp.<br />But I did manage to convert the Battery signal from 9-15V to 0-5V, using a zener diode on approx 7.1V. But I agree that using OpAmp is safer and will surely cause lower drain on my batts.<br /><br />I will update this post once I have a design that works]]></description>

			<description><![CDATA[The RTC libraries don't do anything with timer1/2.  They are all just read and write routines to various addresses on the Chronodot.<br /><br />When I run an example sketch for either Chalieplexing  or RTC stuff, adding in only the minimum code to make the other component work, and INITing causes the conflict.<br /><br />Considering that these 2 items seem to be a natural fit, I am surprised that no one else has had this issue...]]></description>

My intent is for all pin connections between the two Arduino boards to have one &quot;reader&quot; and one &quot;writer,&quot; but you're saying that my reader is not at hi-Z, so the reader is grounding the same line that the writer is trying to assert. Do I have that right?]]></description>

			<title>Re: Scaling a 0-15V analog signal for max resolution</title>
			<description><![CDATA[I think you can live with the source voltage changing as long as it changes slowly.<br /><br />You will still have a divider no matter what you do.  If you run the output of the divider directly into an ADC pin, you will have to keep the impedance (resistance in this case) below 10K.  With an opamp, you can use higher values in your divider and thus reduce the battery drain while still keeping the impedance low.  <br /><br />Also, you wanted better resolution in the voltage range that you cared about, 9-15V.  Given the title of your post, I assumed it was the most important thing to you.  That is what the differential op amp config will do.]]></description>

			<description><![CDATA[Thank you!<br /><br />I did do a simple test with an led, and yes once the BOD level is reached it does set the pin low, turning the led off. <br /><br />Are you suggesting a MOSFET because it can handle more power? less ware over time*<br />There then poses an issue, the threshold is a little less than 2.5 volts, but if I have the BOD set to 1.8 volts will the strip turn off before the BOD initiates?]]></description>

			<title>Re: arduino wave shield and continous servo motor</title>
			<description><![CDATA[<blockquote class="uncited"><div>It created this path to/and made the directory libraries with all examples: C:\Users\cappy\Documents\Arduino\arduino-1.0\libraries I moved the files and put them under the Arduino Dir and deleted arduino-1.0.</div></blockquote><br />Not sure what you are saying exactly.  There are 2 &quot;Libraries&quot; folders:<br /><br />1) Is under the Arduino-xxx install folder and contains all of the standard libraries for the Arduino IDE.  They should stay in that folder.<br /><br />2) Is under your &quot;MyDocuments/Arduino&quot; folder that is used for libraries that you download.  This is where WaveHC and ServoTimer2 folders should be.<br /><br />The reason for having a separate &quot;Libraries&quot; folder for your downloaded libraries is so you don't have to move them around between different versions of the IDE.<br /><br />One thing to try is change:<br /><dl class="codebox"><dt>Code: <a href="#" onclick="selectCode(this); return false;">Select all</a></dt><dd><code>#include &lt;ServoTimer2.h&gt;&nbsp; // the servo library</code></dd></dl><br />to<br /><dl class="codebox"><dt>Code: <a href="#" onclick="selectCode(this); return false;">Select all</a></dt><dd><code>#include &quot;ServoTimer2.h&quot;&nbsp; // the servo library</code></dd></dl><br /><br />If you can provide a link to the exact version of ServoTimer2 that you are using, I can try to reproduce the problem here.]]></description>
