Generally speaking, my sound system will consist of two parts:melody generator;speech generator. The latter will be discussed in a future article, but today (and n...en-USTelligent Community 12https://community.element14.com/learn/learning-center/stem-academy/stem-projects/b/blog/posts/shedule-homework-robot---sound-system-s-hardware-part-2Tue, 19 May 2015 17:29:06 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:72cf0e7b-3345-4efa-86d3-30192f8d5cfeanujaapte1<p>Here&#39;s a tutorial that may be relevant - <a class="jive-link-blog-small" href="/products/arduino/b/blog/posts/create-your-own-music-with-simulink-and-arduino">Create your own music with Simulink and Arduino</a></p><img src="https://community.element14.com/aggbug?PostID=20832&AppID=195&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/learn/learning-center/stem-academy/stem-projects/b/blog/posts/shedule-homework-robot---sound-system-s-hardware-part-2Thu, 14 May 2015 19:23:15 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:72cf0e7b-3345-4efa-86d3-30192f8d5cfeDAB1<p>Are you going to use a real time clock chip to keep track of days and hours or just run off of the board clock?</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=20832&AppID=195&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/learn/learning-center/stem-academy/stem-projects/b/blog/posts/shedule-homework-robot---sound-system-s-hardware-part-2Thu, 14 May 2015 16:35:44 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:72cf0e7b-3345-4efa-86d3-30192f8d5cfeRobert Peter Oakes1<p>have you looked at using an R-2R ladder for the resistor network, it would simplify the DAC by only requiring 2 resistor values and is a common technique for making DACS</p><p><a href="http://upload.wikimedia.org/wikipedia/commons/4/41/R2r-ladder.png"><img height="121" src="http://upload.wikimedia.org/wikipedia/commons/4/41/R2r-ladder.png" width="482" alt=" " /></a></p><p>&nbsp;</p><p>See the WIKI page for more details <a class="jive-link-external-small" href="http://en.wikipedia.org/wiki/Resistor_ladder" rel="nofollow ugc noopener" target="_blank" title="http://en.wikipedia.org/wiki/Resistor_ladder">Resistor ladder - Wikipedia, the free encyclopedia</a></p><p>&nbsp;</p><p>Hope this helps</p><p>Good luck</p><p>&nbsp;</p><p>peter</p><img src="https://community.element14.com/aggbug?PostID=20832&AppID=195&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/learn/learning-center/stem-academy/stem-projects/b/blog/posts/shedule-homework-robot---sound-system-s-hardware-part-2Thu, 14 May 2015 16:07:04 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:72cf0e7b-3345-4efa-86d3-30192f8d5cfedragonstyne0<p>Nice job so far Yuri.</p><p>&nbsp;</p><p>[][][]Steve</p><img src="https://community.element14.com/aggbug?PostID=20832&AppID=195&AppType=Weblog&ContentType=0" width="1" height="1">
