However, the Raspberry Pi is also capable of direct servo control. To achieve this, we will make use of Richard Hurst's ServoBlaster, which is a multiple servo driver.

In this recipe, we will control four servos attached to the MeArm, a simple laser-cut robot arm; however, you can choose to fit servos to whatever device you like:
