I am working on a project and need a servo that rotates 360*. Here is what i would like to accoumplish. Have 4 pir sensors pointed in 4 different directions. When one of those senses movement my arduino uno will tell a servo to turn to that sensor. And i will have a camera mounted to it also to take a pic. So my question is.... does someone make a servo that would work for my project? Thanks for your help!
Be very careful in your selection of a servo that will do what you need it to do. Vendors are not consistent on what they mean by "360 degree servo". Some mean it's a modified continuous rotation servos that no longer can be commanded to go to a specific position and stop there, but rather have been modified to be a simple bi-directional variable speed geared motor drive assembly, I call these latter ones ex-servos. Others when calling their product a 360 degree servos mean a standard servo that has a full positioning range of 0-360 degrees, which is what your application calls for. And don't be surprised that no matter how careful you are in your servo selection, what you end up getting is a continuous rotation instead of a standard servo with 360 degree travel stop, such is the state of servo vendor descriptions and specifications of their products.
