Arduino Stand Alone on Fritzing?

I am developing an speedometer and I have already the project done in my Arduino! It's nice...
However, now it's time to go to the second step of my project, and try to do do it as stand alone...It could be good to have my own PCB.
Has anyone already done a similar project? Some link or files available could be very helpful.
Thanks in advance

i used this for reference

Thanks, very useful link :wink:

Anyway...Has anyone developed already an speedometer? I am interested in compare my project with similars.
Thanks in advance
