I also have an 8 sensor version - the OctoSonar.\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\/octosonarx2\/\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 80 header pins - soldering required.\u003c\/p\u003e","brand":"Red Hunter Store","offers":[{"title":"Default Title","offer_id":43965890986044,"sku":"RHS-OCTCON16-OPDS","price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/1810\/3356\/files\/il_fullxfull.3618290820_oy6a_f63698c2-155d-4de9-987b-85dad81c78f5.jpg?v=1770534463","url":"https:\/\/store.redhunter.com\/products\/octosonarx2-connect-16-x-hc-sr04-to-52497","provider":"Red Hunter Store","version":"1.0","type":"link"}
