Working with motors: DC motors/products/arduino/b/blog/posts/working-with-motors-dc-motorsIn one of my last posts I have shown how to drive a servo motor. Servo motors comes in two flavours: the standard servo motors can be set such that they reach a given position and maintain it; the continuous rotation servo can rotate continuously at en-USTelligent Community 12RE: Working with motors: DC motorshttps://community.element14.com/products/arduino/b/blog/posts/working-with-motors-dc-motorsSat, 21 May 2016 12:20:37 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:2de663bc-753a-427f-8f58-3fe471b8f5b6tonyboubady0<p>Exactly same as my Smart Headlight concept, driving series of LEDs with NPN transistor here <a class="jive-link-blog-small" href="https://www.element14.com/community/groups/roadtest/blog/2015/12/30/ti-and-w%C3%BCrth-elektronik-led-roadtest--the-schema--510">TI and Würth Elektronik LED RoadTest+ - The Schema - 5/10 </a> once you have understand the basic concept then you can drive anything using transistors... <span>[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-2de663bc-753a-427f-8f58-3fe471b8f5b6/contentimage_5F00_3.png:16:16]</span> </p><img src="https://community.element14.com/aggbug?PostID=1253&AppID=145&AppType=Weblog&ContentType=0" width="1" height="1">RE: Working with motors: DC motorshttps://community.element14.com/products/arduino/b/blog/posts/working-with-motors-dc-motorsWed, 18 May 2016 16:43:47 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:2de663bc-753a-427f-8f58-3fe471b8f5b6shabaz1<p>Regarding the last paragraph, this circuit needs an NPN BJT. PNP won&#39;t work, due to PNP being biased permanently on if the input is from an Arduino.</p><img src="https://community.element14.com/aggbug?PostID=1253&AppID=145&AppType=Weblog&ContentType=0" width="1" height="1">RE: Working with motors: DC motorshttps://community.element14.com/products/arduino/b/blog/posts/working-with-motors-dc-motorsTue, 03 May 2016 10:15:48 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:2de663bc-753a-427f-8f58-3fe471b8f5b6kulky640<p>You should put a diode in parallel with the motor (or any other inductive load) to prevent damage to the transistor by voltage spikes that are created when the tranistor opens.</p><img src="https://community.element14.com/aggbug?PostID=1253&AppID=145&AppType=Weblog&ContentType=0" width="1" height="1">
