@aminafshar1 Hi. Ive an arduino pro mini with a GY-NEO6MV2 NEO-6M GPS Module running a sketch that extracts speed over ground and deflects a servo. Its a dashboard speedo gauge, is that what you had in mind..? Happy to share any code. Gps module is from amazon. Not sure about acceleration but I can check. The gps outputs NMEA sentences.

I find that for things like that it's best to do an internet search which usually throws up lots of useful stuff.
