If you are willing to accept a few limitations, there are expansion options that can provide both convenience and power beyond what standard Arduino shields offer.
This simple implementation provides a lot of functions that even beginners can sink their teeth into.
This “handy” glove can help with communication, as well as be a wireless controller in all sorts of applications.
The unique DC servo design described in this article uses a stepper motor as if it were a DC motor, and can be implemented with minimal electronics.
Part 2 of our quadcopter build goes over the design and parts breakdown.

Linear Actuators, Servos, and Motion Devices
In last month's column, I reviewed the typical rotary servos that we are so familiar with — those used as actuators for model airplane control surfaces or as drive motors for smaller tabletop robots. I also reviewed a few very large servos such as the Invenscience Torxis monster servos and a few tiny servos that weigh only a few grams each. This month, I would like to review a type of servo or actuator that not many of us ever implement into our robotic creations: linear servos and actuators. Page 74
