gear motor arduino Gravity: DC Micro Metal Gear Motor w/Driver For Arduino - 30:1 [discontinued]An ordinary DC motor requires an H Bridge to work with a microcontroller such as an arduino UNO. For newcomers to electronics, the process of finding the right motor driver, connecting it to the MCU and learning the relevant electronic theory can be confusing and frustrating when you just need something to work quickly. We hope that using the DC Micro Metal gear motor changes this. The new micro DC geared motor is easy to operate using the DFRobot
An ordinary DC motor requires an H Bridge to work with a microcontroller such as an arduino UNO. For newcomers to electronics, the process of finding the right motor driver, connecting it to the MCU and learning the relevant electronic theory can be confusing and frustrating when you just need something to work quickly. We hope that using the DC Micro Metal gear motor changes this.
The new micro DC geared motor is easy to operate - using the DFRobot "Gravity" interface, you are able to control the motor using only one control signal. Easily implement forward/reverse control and speed control via PWM. This motor also combines the features of a DC motor and 360 degree servo. We have also increased the stop range and reduced standby power consumption, so the current draw is less than 1mA without signal control. The Arduino Servo library supports up to 12 motors on most Arduino boards and 48 on the Arduino Mega. More fucntion could be found on Arduino Servo page. Ideal for DIY projects!
NOTE: The embedded control chip will consume a small amount of the input voltage, therefore the motor voltage will be slightly reduced. The motor speed will also be slightly slower than the rated motor speed.

Very nice for the price
Color: Jelly Pink, Size: 8"W, Color: Jelly Pink, Size: 8"W
This is a very nice jewelry case, especially for the price (around $10). I want to note that it is top heavy; even without the mirror inside the top part it tips over (won't sit flat on the bottom part when open, most of the time). There are some minor imperfections in the case, but nothing that will prevent it from doing its job and it still looks really nice.
The necklace pocket does not have any dividers, it's one pocket.
The zipper tabs look like they were painted, I'm not sure what material is underneath, but I'm hoping it does not chip over time.
The stitching on the case looks nicely done.

Perfect for travel. Sturdy and will keep your items safe.
Color: Cloud White, Size: 8"W, Color: Cloud White, Size: 8"W
This was a galentines gift for a gift exchange.
It comes with multiple compartments that are removable and can hold any type of jewelry from studs to necklaces, rings and bracelets.
Any solid bracelet takes some maneuvering to hold.
This is semi customizable to fit your needs and will house most jewelry items.
The zipper does get stuck a bit but is a strong thick zipper and not super flimsy.
The inserts on the sides can be removed, however, the ring inserts seem to be glued down.
Bigger jewelry or chunky jewelry pieces may not fit well in this travel case.
All in all it can hold quite a bit, the size is compact and perfect for travel and it’s a handy organizer for jewelry.

Great Value For The Money
Color: White
I needed something to present my daughter's upcoming 18th birthday gift in. It's a charm bracelet and a bunch of individual meaningful charms. None of them come in gift boxes, and I want something to present them all together in. Failing to find a gift box to fit the bill, I thought that this cute jewelry box would be a nice alternative. I am pleasantly surprised at what I received for the price. I expected a flimsy cardboard-ish box, and this is not that. It's not heirloom quality, but it is a nice sturdy box, well put together, and the interior tray and dividers are thick. Interior fabric is nicely soft and velvety. The box is larger than I expected, it will hold a good amount of jewelry, and it's pretty and of much better quality than I anticipated. Will certainly make a very nice presentation for my daughter's gift, and she'll be able to use it for many years, I'm sure.

Not your average jewelry box....
Color: Sage Green
A lovely simple yet elegant jewelry box - nicely made with a practical design. It has substantial weight and opens and closes nicely. This sage green color is muted with a matte finish making it soft in appearance. The gold closure adds just the right amount of interest. I placed a beautiful pendant inside as a surprise and together, these made the perfect gift for a 40th birthday. Would buy again!
