I&amp;#39;m working on my project and it involves driving a servo motor using an MCB900 board. Is it possible to directly connect the servo motor to one of the ports or do I have to use an interface like an amplifier. 
Your response will be appreciated</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Driving a servo motor</title><link>https://community.arm.com/thread/73411?ContentTypeID=1</link><pubDate>Wed, 10 Aug 2005 18:22:09 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:b40595ac-d47a-4710-9d07-5d4d813c1190</guid><dc:creator>Ade Popoola</dc:creator><description>&lt;p&gt;Hi Erik,&lt;br /&gt;
The MCB900 board is an 8051 microcontroller board basically used for training.&lt;br /&gt;
The servo motor requires a voltage of 4.8v to 6v to drive it.&lt;br /&gt;
Also, if I may ask, what is the output voltage of the 8051 ports.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Driving a servo motor</title><link>https://community.arm.com/thread/97373?ContentTypeID=1</link><pubDate>Wed, 10 Aug 2005 12:18:26 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:734e5627-7c0d-4183-a3e8-1dd295b4cf72</guid><dc:creator>erik  malund</dc:creator><description>&lt;p&gt;I missed that one, a distributor even gave me one of the MCB900s.&lt;br /&gt;
&lt;br /&gt;
&lt;i&gt;Is it possible to directly connect the servo motor to one of the ports or do I have to use an interface like an amplifier.&lt;/i&gt;&lt;br /&gt;
&lt;br /&gt;
The answer is 99% NO and for the last 1% risky.&lt;br /&gt;
&lt;br /&gt;
There are strong EMF forces involved in driving a motor and no uC I know of is designed to withstand that.&lt;br /&gt;
&lt;br /&gt;
Also is this a 3V motor? haven&amp;#39;t seen many of those.&lt;br /&gt;
&lt;br /&gt;
For motor drivers I would check Allegro semiconductors, that is their specialty.&lt;br /&gt;
&lt;br /&gt;

if so - wrong forum&lt;br /&gt;
If not - please provide a link&lt;br /&gt;
