Digital and analog servo's
September 24, 2010
I have some questions regarding servo's and maybe someone can share the knowledge with me?
I want to buy an Arduino Mega board and several servo's for my ultimated goal (a hexapod). But I see that there are analog and digital servo's. So I have some questions wich I can't find the answers to.
1) What is the different between them? and what is the best one for a leg?
2) Do they connect to the same way on the arduino board? Because I saw some scheme's connecting it direct to the digtal port and some that has a resistor bank between them?
3) When programming the software, do you need to take in mind that it is a digital or analog servo?
Thanks in advance
