Hobby Motor with Encoder - Metal Gear (DG01D-E)
OOD!
Price: $10.90

Availability: Back Order
Sparkfun Item #: ROB-16413 -

The DG01D-E is a single hobby motor with a hall speed encoder. This motor requires a voltage between 3-9V, has a gearbox ratio of 1:48 and a speed of 90RPM at 4.5V. The voltage between positive and negative is determined according to the power supply voltage of the single chip microcomputer used, generally 3.3V or 5V is used. The hall sensor can sense the North and South poles of its magnetic plate. When the hall sensor senses the South of the magnetic plate, the hall output will result in a...

Slide Pot - Motorized (10k Linear Taper)
Price: $45.05

Availability: Stocked
Sparkfun Item #: COM-10976 -

These motorized sliders are very cool. Each is essentially a standard slide pot which is belt-driven by a small motor. The slide contains two separate 10k linear taper potentiometers so that you can use one as servo-feedback in order to read the position of the slider and use the other to control whatever your target is. There is also a touch sense line which is electrically connected directly to the metal slider tab so that you can interface the slider with capacitive touch circuitry....

Solenoid - 12V (Latch / Lock)

Sparkfun Item #: ROB-15324 -

Does controlling door and cabinet access with the power of Electromagnetism interest you? Excellent! In effect, this latch / lock solenoid is an electronic lock. When powered with 12VDC source, the latch is pulled in, allowing movement. Without power, the latch is extended, blocking movement and your secret drawer is safe and secure. This Solenoid Latch comes with a mounting bracket which can be removed with two screws. Once removed the solenoid can be rotated 180 and remounted. Paired with a...

Solenoid - 36v

Availability: Stocked
Sparkfun Item #: ROB-10391 -

Solenoids are a great way to induce linear motion for pushing, pulling or controlling switches and levers. According to the datasheet this solenoid is rated for 36V but they work like a charm at 12V. We've been controlling them with the Arduino Power Driver Shield, there's even some example code below. With a throw of 10mm these solenoids are great for all kinds of motion applications such as actuating door latches, automating percussion instruments or just poking people. At 12 volts these...

Solenoid - 5V (Small)
Price: $8.94
View
Availability: Stocked
Sparkfun Item #: ROB-11015 -

Solenoids are a great way to induce linear motion for pushing, pulling or controlling switches and levers. This smaller solenoid is designed to work directly with 5V which makes it a great match for embedded projects. It has a throw of about 4.5mm and 2 M2 mounting holes on the body. The wire lead is about 2" long and is terminated with a 2-pin JST PH connector. Note: The mounting holes on this solenoid are actually 1.6mm in diameter. This will allow you to tap for an M2 screw. Also, although...

Vibration Motor

Availability: Back Order
Sparkfun Item #: ROB-08449 -

A vibration motor! This itty-bitty, shaftless vibratory motor is perfect for non-audible indicators. Use in any number of applications to indicate to the wearer when a status has changed. All moving parts are protected within the housing. With a 2-3.6V operating range, these units shake crazily at 3V. Once anchored to a PCB or within a pocket, the unit vibrates softly but noticeably. This high quality unit comes with a 3M adhesive backing and reinforced connection wires. Documents: Datasheet ...
