LM393 Comparator Integrated Circuit: it consists of two independent precision voltage comparators. Its role is to compare the two input voltage based on input\/output voltage level. It control the motor' s operation and correct the direction of the car. DC Motor Driver with Gear Reduction: It can control the speed of smart robot car to avoid running too fast. In the process of assembly , we can not only be familiar with the principle of mechanics, but also can gradually learn: photocell, voltage comparator, motor drive circuit and other related electronic information. Specification: Motor Length: 62mm\/2.44 inch Battery Box Size: 56x30mm\/2.20x1.18inch Package Includes: 1 piece Robot Car Chassis Kit\u003c\/p\u003e","brand":"Shop2IndiaBei","offers":[{"title":"Default Title","offer_id":43064303747240,"sku":"U2I-BFU-73006368","price":2509.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/1588\/1354\/products\/73006368_12_image__93249.jpg?v=1673085386","url":"https:\/\/shop2india.com\/products\/2wd-smart-robot-car-chassis-kit-diy-for-arduino-tracking-line-following-function","provider":"SHOP2INDIA GATEWAY","version":"1.0","type":"link"}
