It looks like a micro servo, it acts like a micro servo, but it's more than just a micro servo! Adafruit got a factory to custom-make these classic 'micro' sized hobby servos with a twist - the feedback (potentiometer wiper) line is brought out to a fourth white wire. You can read this wire with an analog input such as those on an Arduino, to get the servo's position. That information can be used in robotics to improve stability or even allow 'recording' of servo motion.
Check out Adafruit's example Arduino sketch which demonstrates how to record motion data to the EEPROM and then play it back when a button is pressed. Comes with a range of horns as seen above.

- How To Control A Motor with the Raspberry Pi
In this tutorial, we are going to connect a Motor to the Raspberry Pi and create a hypnotic self-spinner. We are first going to look at how to wire the Raspberry Pi to the motor controller and the motor. We will then look at using the raspberry pi to...
- The Maker Revolution
The Maker Revolution celebrates the creation of new devices and the modification of existing ones - the transition from a consumer buying goods to eventually having a major part in their creation. The Maker Revolution places strong emphasis on free (...
- Motor Drivers vs. Motor Controllers
If you’ve ever built a robot with wheels, or any motorised parts really, you’ll have come across the issue of needing to drive it from your microcontroller. Because a standard chip is only able to output a small amount of current, you&rsq...
- Controlling Servo Motors with Arduino
Servo motors are extremely useful in so many different applications; it’d be good to learn how to control them! Solenoid and DC motor control have been shown already; for the most part, they are both pretty straightforward (only power and groun...
- DIY Pi Buggy
The motivation behind this project came from a robotics and engineering club that I've been going to. I've been saving my money and building up an understanding of raspberry pi and electronics. The reason I chose this project was to get used to using motors and controlling different speeds. I am self taught as I am home schooled and my mum and dad (who are my teachers) don't understand how to use the raspberry pi! The project is...
- Accelerometer Controlled Animatronic Finger
This project incorporates two Arduino boards, in a Master/Slave setup. The master is one with an accelerometer (ADLX345) and the slave has a Servo attached (SG90). When tilting the accelerometer, the master Arduino tells the Slave Arduino to rotate the servo. This is a great way to learn slave and master serial communication. ...
