I now also have a 16 sensor version - the OctoSonarX2.\u003c\/p\u003e\n\u003cp\u003eWhy did you make it?\u003c\/p\u003e\n\u003cp\u003eI wanted more sensors on my robot to help it navigate. I'm too cheap to buy a mega board with enough pins or smarter sensors that need less pins.\u003c\/p\u003e\n\u003cp\u003eWhat makes it special?\u003c\/p\u003e\n\u003cp\u003eThe library handles all the timing, and the hardware interrupts provide surprisingly high accuracy. Each unit is individually tested using an Arduino test-bed and ships with separate pin headers.\u003c\/p\u003e\n\u003cp\u003eSource code and links to instructions at https:\/\/github.com\/arielnh56\/OctoSonar\u003cbr\u003e\nDocumentation at https:\/\/octosonar.com\/documentation\/octosonar\/\u003c\/p\u003e\n\u003cp\u003eNote that this is currently only compatible with AVR based Arduinos (UNO, Nano etc. not the new SAMD21 boards e.g. MKR) This is a software issue that needs debugging\u003c\/p\u003e\n\u003cp\u003eIncludes 40 header pins - soldering required.\u003c\/p\u003e","brand":"Red Hunter Store","offers":[{"title":"Default Title","offer_id":43965891051580,"sku":"RHS-OCTCON8-QPDS","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/1810\/3356\/files\/il_fullxfull.3617984550_as10_0120e384-3803-4088-b8ce-68c4346dffbe.jpg?v=1770534469","url":"https:\/\/store.redhunter.com\/products\/octosonar-connect-8-x-hc-sr04-to-arduino-19630","provider":"Red Hunter Store","version":"1.0","type":"link"}
