I really prefer stepper motor x27.168 over any servo. I dont have any needle servo moved. Every needle is a darsonval or stepper motor x27.168, which are used in automotive cockpits.GrubbyZebra wrote:Very excited to come across this project. I recently bought a TAS Indicator that had a broken bourdon tube (yay $40 real aircraft gauge!) I am pretty confident in how to get the mechanical stuff functional again (although I have to make a new card with the right speeds for the PA24-250), but am lost on the arduino side of it. Do you have a primer (or a site you referenced), or could you make one, explaining how to use and Arduino to drive a servo-actuated gauge?
You can find a lot of info about driving both of them in arduino sites. Just google "arduino servo".. and you get a lot of info.
Servos are very easy to interface, but the movment is not smooth.
