I simply played with the leads with a suitable battery and watched what happens when different leads are connected. Then I learnt how a transistor can switch between leads, noticing that some combinations cause smoke. Then I learnt about 'H' bridges, where 4x transistors are switch by enable and ON and OFF. I found this really interesting and made robots, all with much help from forums like this.<br /> <br /> The Arduino route is much faster and there's plenty of examples and help, and using drivers is also easier. I'm still glad I chose the PIC route though, as I learnt more I think.<br /> <br /> Let us know which route you prefer, I may be able to help you with th PIC choice.<br /> Cheers, C.</div> </div> <div

I don't mind buying some new kit or shields if needed\nThanks everyone, stay safe & healthy", "answerCount": 4, "upvoteCount": 0, "author": { "@type": "Person", "@id": "https://www.electro-tech-online.com/members/carl25.328086/", "name": "carl25", "url": "https://www.electro-tech-online.com/members/carl25.328086/" }, "suggestedAnswer": [ { "@type": "Answer", "datePublished": "2024-11-24T10:06:00+00:00", "url": "https://www.electro-tech-online.com/posts/1457788/", "text": "If you are just rotating things by a limited amount, rather than continuous movement, radio control type servos would be far simpler.\n\nControlling those from a microcontroller is very simple & no extra hardware or drivers are needed.\n\nHi,\nAlso I think the signals can be in parallel so all of the servos will move together.\nC", "upvoteCount": 0, "author": { "@type": "Person", "@id": "https://www.electro-tech-online.com/members/camerart.91879/", "name": "camerart", "url": "https://www.electro-tech-online.com/members/camerart.91879/" } }, { "@type": "Answer", "datePublished": "2024-11-24T09:54:27+00:00", "url": "https://www.electro-tech-online.com/posts/1457784/", "text": "If you are just rotating things by a limited amount, rather than continuous movement, radio control type servos would be far simpler.\n\nControlling those from a microcontroller is very simple & no extra hardware or drivers are needed.", "upvoteCount": 0, "author": { "@type": "Person", "@id": "https://www.electro-tech-online.com/members/rjenkinsgb.273344/", "name": "rjenkinsgb", "url": "https://www.electro-tech-online.com/members/rjenkinsgb.273344/" } }, { "@type": "Answer", "datePublished": "2024-11-23T09:54:42+00:00", "url": "https://www.electro-tech-online.com/posts/1457755/", "text": "There are lots of Arduino to Stepper motor tutorials out there, the one below using a common driver module which will be similar / compatible to ones you probably have.\n\nIf you build up a single driver as shown in the tutorial then think you will soon work out that you can program up the code to control the 5 you want for both speed and timing intervals.\n\nhttps://howtomechatronics.com/tutorials/arduino/stepper-motors-and-arduino-the-ultimate-guide/", "upvoteCount": 0, "author": { "@type": "Person", "@id": "https://www.electro-tech-online.com/members/wp100.117244/", "name": "Wp100", "url": "https://www.electro-tech-online.com/members/wp100.117244/" } } ] }, "publisher": { "@type": "Organization", "name": "Electronics Forum (Circuits, Projects and Microcontrollers)", "description": "An electronics forum to talk all about circuits and projects.", "url": "https://www.electro-tech-online.com" } } </script>  <noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-MMC9PJ9" height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>   <noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-KLX5R59" height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>  <script> $(function(){ var notice = $('.xb-welcome-notice'); if(notice.length){ var cookie = XF.Cookie.get('hide_welcome_notice'); if(!cookie){ XF.Cookie.set('hide_welcome_notice', Date.now()); notice.show(); } else if ((Date.now() - cookie) > 8.64e+7){ XF.Cookie.set('hide_welcome_notice', Date.now()); notice.show(); } else { notice.hide(); } } }); </script> </div> </body> </html>
