A PWM output consists of a series of alternating high and low signals, with them on and off. The speed of a DC motor depends on the voltage applied across its terminals and the direction depends on the polarity of the applied voltage. Herewith the help of two 555 timer ICs, we are controlling the speed as well as the direction of the dc motor using the above principle.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eH-Bridge with PWM using 555 Timer\u003c\/strong\u003e IC are two 555 timer ICs used. Both IC used as astable multivibrator mode. H-bridge circuits are used to drive motors since they can be varying direction as well as speed. A simply H-bridge schematic circuit drives a motor clockwise \/ anticlockwise by a variable resistance (preset).\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eH-Bridge 555 Timer Kit\u003c\/strong\u003e value of the preset is 10-kilo ohm and reduces the speed to zero when the preset is in mid-position. Depending on the position of the preset, the direction, as well as speed of the motor, can be controlled. The difference in voltage between two points of the motors defines the speed of the motor. If the difference becomes negative the direction gets changed.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv style=\"text-align: start;\" id=\"p_info\"\u003e\u003cimg src=\"https:\/\/i.postimg.cc\/g0cfsyL2\/LGKT094.jpg\" alt=\"h-bridge-with-pwm-using-555-timer-block-diagram\" border=\"0\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimensions (cm) L x W x H : 20 x 15 x 5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eProduct Video\u003c\/h3\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/3jTkjUh7PgE\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/6rmErwU5E-k\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/Fp37DPZVdRI\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF","offer_id":40708850679989,"sku":"LGKT094","price":699.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708850712757,"sku":"LGKT094_R","price":899.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/h-bridge-pwm-arduino.jpg?v=1633434175","url":"https:\/\/kitsguru.com\/fr\/products\/h-bridge-with-pwm-using-555-timer","provider":"KitsGuru","version":"1.0","type":"link"}
