Windshield wiper motors are available around the world, they a very strong and durable. They are easy to control with a few electronic components which are not very expensive and available around the world as well.<\/p>\n<p>I decided to use an ESP8266 NodeMCU as micro controller unit. This MCU is very cheap and has a build in WIFI module. With the I\u00b2C bus of the ESP8266 it is very easy to connect sensors, controllers and even a cheap OLED display to show some status information\u2019s.<\/p>\n<p>To control the motor driver I have chosen a PCA9685 servo controller. With this controller it is very easy to generate a HIGH signal and a PWM signal. With the HIGH signal I am able to set the rotation direction. With the PWM signal the speed of the windshield wiper motor is controlled.<\/p>\n<p>As motor driver I have chosen a very strong one the BTS7960B. I have already used them in different robots with strong 12V DC motors. This BTS7960B motor driver is perfect to control a windshield wiper motor for a long time.<\/p>\n<p>I do not have a step down-converter to generate 5V out of the 12V to power the electronics. That\u2019s the reason why I am using a Power Bank in my test setup.<\/p>\n<p>The picture below shows my test setup to develop the software and to test the windshield wiper motor.<\/p>\n<div id=\"attachment_10479\" style=\"width: 310px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.blogyourearth.com\/wp-content\/uploads\/2020\/04\/DIY_ventilator_construction_wiper_motor_control.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-10479\" class=\"size-medium wp-image-10479\" src=\"https:\/\/www.blogyourearth.com\/wp-content\/uploads\/2020\/04\/DIY_ventilator_construction_wiper_motor_control-300x225.jpg\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/www.blogyourearth.com\/wp-content\/uploads\/2020\/04\/DIY_ventilator_construction_wiper_motor_control-300x225.jpg 300w, https:\/\/www.blogyourearth.com\/wp-content\/uploads\/2020\/04\/DIY_ventilator_construction_wiper_motor_control-1024x768.jpg 1024w, https:\/\/www.blogyourearth.com\/wp-content\/uploads\/2020\/04\/DIY_ventilator_construction_wiper_motor_control-768x576.jpg 768w, https:\/\/www.blogyourearth.com\/wp-content\/uploads\/2020\/04\/DIY_ventilator_construction_wiper_motor_control-1080x810.jpg 1080w, https:\/\/www.blogyourearth.com\/wp-content\/uploads\/2020\/04\/DIY_ventilator_construction_wiper_motor_control.jpg 1200w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-10479\" class=\"wp-caption-text\">DIY ventilator construction wiper motor control<\/p><\/div>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_83 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.blogyourearth.com\/en\/fight-covid19\/windshield-wiper-motor-control-diy-workaround-bridge-ventilator-project-vs-coronavirus\/10478\/#Wires_and_Software\" >Wires and Software<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.blogyourearth.com\/en\/fight-covid19\/windshield-wiper-motor-control-diy-workaround-bridge-ventilator-project-vs-coronavirus\/10478\/#Video\" >Video<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.blogyourearth.com\/en\/fight-covid19\/windshield-wiper-motor-control-diy-workaround-bridge-ventilator-project-vs-coronavirus\/10478\/#Summary\" >Summary<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Wires_and_Software\"><\/span>Wires and Software<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The program to test the basic functionality of the windshield wiper motor is developed to run on an ESP8266 NodeMCU.
