As professional pumps are very expensive, I wanted to share this project to allow people with a small budget but in need of a precision dosing pump for their research, watering plants, aquariums, hobby or any other liquid pumping applications. So comment, share, suggest optimizations, try it and let us all know what you think \ud83d\ude09<\/li><\/ul>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">More Info<\/h2>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Visit my pages for updates and more informations (simple schematics on how to drive the stepper if you don\u2019t want to use the Arduino are provided here):<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/karim.lakras.eu\/index.php?page=hobbies&amp;lang=en&amp;cat_hob=peristaltic\">https:\/\/karim.lakras.eu\/index.php?page=hobbies&amp;lang=en&amp;cat_hob=peristaltic<\/a><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Videos<\/strong><\/h4>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"3D printed peristaltic pump - Nema 17\" width=\"1200\" height=\"900\" src=\"https:\/\/www.youtube.com\/embed\/k6mOiT1_ZLY?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"3D printed peristaltic pump Nema 17 - more info\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/oCNA98Bd8yQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Names &amp; references<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">I found many useful posts and informations about the arduino, here is some useful links:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<pre class=\"wp-block-verse\"><a rel=\"noreferrer noopener\" href=\"https:\/\/howtomechatronics.com\/tutorials\/arduino\/lcd-tutorial\/\" target=\"_blank\">https:\/\/howtomechatronics.com\/tutorials\/arduino\/lcd-tutorial\/<\/a><\/pre>\n\n\n\n<pre class=\"wp-block-verse\"><a rel=\"noreferrer noopener\" href=\"http:\/\/www.rinkydinkelectronics.com\/library.php\" target=\"_blank\">http:\/\/www.rinkydinkelectronics.com\/library.php<\/a><\/pre>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\">Thanks to Henning Karlsen for his help with some of his libraries.
