Use the Ethernet library to write sketches which connect to the internet using the shield. The new Ethernet shield now includes a micro SD card connector, it is MEGA compatible and an on-board reset controller. The ethernet shield connects to an board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top.uses digital pins 10, 11, 12, and 13 (SPI) to communicate with the W5100 on the ethernet shield.

Beware of poor quality issues!
Color: Orange - 3.15Inch, Color: Orange - 3.15Inch
Got limited use out of ball, seemed to have quite a strong motor and was going to be a good buy. But upon going to recharge it for the first time, discovered the USB port was completely loose/not attached. Will steer clear of this brand going forward.

The Ball Never Gets Boring
Color: Tangerine - 3.15Inch
My dog was immediately curious about this ball, and that curiosity turned into a surprisingly long play session. The movement keeps things unpredictable enough that it holds attention longer than a standard toy. I liked that it encouraged activity without requiring me to constantly throw something across the room. The textured surface also seemed easy for my dog to grab and carry around. One thing I noticed is that hard floors allow the ball to move around much more dramatically than carpet. It feels sturdy enough to handle enthusiastic play and occasional chewing. The bright color makes it easy to spot when it inevitably ends up under furniture. Charging was simple and didn’t become a hassle.

Tough build for rowdy play sessions
Color: Tangerine - 3.15Inch
I picked up this motorized E-TPU dog ball last Thursday to keep my German Shepherd occupied during my afternoon video conferences in Folsom. The product quality is evident in the spongy, high-density foam construction, which provides a satisfying grip for his jaws without sustaining a single tear or puncture. The built-in motion sensor is highly responsive, sending the ball into an unpredictable frenzy of hops and spins whenever it gets nudged. It offers excellent value for money because the structural integrity holds up perfectly against aggressive chewing that would normally shred standard rubber toys in minutes. For a parent or professional needing a functional, autonomous distraction to burn off their pet's excess energy indoors, this rugged smart toy delivers a very reliable and quiet performance.

My dog really likes it
Color: Tangerine - 3.15Inch
My golden retriever has a lot of energy, especially on rainy days when we can’t stay outside for long. This rolling ball has been a fun way to keep him entertained indoors. The movement is unpredictable enough to keep him interested, and he’ll follow it around the living room until he’s ready for a nap.
The material has held up well to daily play, and it’s easy to recharge when needed. Watching him chase it around has honestly been entertaining for the whole family. Great toy for keeping active dogs busy.
What I like most is that it gives him something to do without needing constant attention from us. The ball rolls on its own, changes direction, and keeps him engaged much longer than some of his other toys. A nice option for dogs that need extra stimulation during the day.

Keeps my puppy happy!!
Color: Orange - 3.15Inch
My 8 month old puppy loves this ball!! He is so happy when we charge it up for him!! It's great because it keeps him busy for a few minutes and it tires him out. This is our second one so we always have one ready to go for him.
