Servos are motors that allow you to accurately control the rotation of the output shaft, opening up all kinds of possibilities for robotics and other projects.

Core Skill: Robotics

This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.

3 Robotics

Skill Level: Competent - You may need an understanding of servo motors and how to drive them. Additionally, you may need some fundamental understanding of motor controllers.

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.

1 DIY

Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

  • Can I operate this servo with 5 VDC? I see some servos operating in the 6-7 VDC range, but my power supply is 5VDC. I don't want to design something that's bound to fail. Thanks!

    • 5V should work. The voltage range for this servo is specified, under the Features tab and datasheet, above is 4.8-6.0 Volts. I have used this servo with a 5V Arduino Uno and it seemed to work fine for me. Though I was only running it for a demo project, so I have no personal experience with long term use.

  • This servo is actually 45 degrees per side (90 degrees in total and not 180 degrees) specified above. I got one and kept trying to make it get to the END (90 degrees). Slightly misleading information there Sparkfun.
