&lt;br /&gt;
More details are required, let&amp;#39;s start with:&lt;br /&gt;
&lt;br /&gt;
 - Details of the DC motor.&lt;br /&gt;
 - How the motor is to be driven.&lt;br /&gt;
 - How the motor speed is monitored.&lt;br /&gt;
&lt;br /&gt;
There are endless variations in each case.&lt;br /&gt;
&lt;br /&gt;
If you have not made up your mind about these details, then tell us about the application.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: how to control the speed of DC motor by using 89c52</title><link>https://community.arm.com/thread/72802?ContentTypeID=1</link><pubDate>Tue, 19 Oct 2004 06:38:32 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:c9315757-9c9d-4dd2-a908-f1df0d3d5d38</guid><dc:creator>Ulf Sa&amp;#195;Ÿ</dc:creator><description>&lt;p&gt;Hallo Stefan!&lt;br /&gt;
Oh, I would be very happy if i could solve all my problems in that straight way.&lt;br /&gt;

&lt;br /&gt;
Press the 89c52 firmly against the motor spindle to slow the motor down, release to speed up. To stop the motor short the supply across a couple of the pins.&lt;br /&gt;
&lt;br /&gt;
Implementation time: 2 seconds.&lt;br /&gt;
Cost: $4.95&lt;br /&gt;
&lt;br /&gt;
Job done!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
