It outputs readings very quickly. From multiple distance readings we can calculate speed (velocity is the derivative of position).\n\nRepository Contents\n-------------------\n\n* **/firmware** - The code that runs on the Arduino\n* **/hardware** - An Arduino shield to easily connect a computer PSU and the 6 wires for the large digit driver backpack\n\nLicense Information\n-------------------\n\nThis design is [OSHW](http://www.oshwa.org/definition/) and public domain but you buy me a beer if you use this and we meet someday ([Beerware license](http://en.wikipedia.org/wiki/Beerware)).","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsparkfun%2Fspeed_trap","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsparkfun%2Fspeed_trap","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsparkfun%2Fspeed_trap/lists"}
