Tomorrow is Arduino Day, and we are joining in on the fun by offering big discounts on many of our Arduino-related products, including our A-Star programmable controllers and Arduino shields. The sale has already started, and it will run through the end of Sunday (I know, Arduino Day is a one-day event, but this makes sure the sale lasts all Arduino Day in every time zone). You can find all of the sale items on our Arduino Day 2015 sale page.
Get FREE copies of Circuit Cellar magazine’s March issue and Elektor magazine’s March/April issue with your order, while supplies last. To get your free issues, enter the coupon codes CIRCUIT0315 and ELEKTOR0315 into your shopping cart. The Circuit Cellar magazine will add 6 ounces and the Elektor magazine will add 9 ounces to the package weight when calculating your shipping options.
Tomorrow is Pi Day (3/14/15 in the standard US date format of month/day/year), and we are celebrating by having a special overly-pi-themed one-day sale:
The sale is live now and runs through the end of tomorrow (midnight Pacific Time).
We received order 1J200000 this morning from Ralf in Germany! However, it turns out that because of a one-time database screwup, this was not actually our 200,000th order (thanks, Paul). We received that one a few minutes later when Alex from Iowa placed order 1J200008. To celebrate, we included a special gift with both of these orders: a prototype of the new Zumo robot we expect to release this month. Congratulations to Ralf and Alex! For everyone else, keep an eye on this blog for more information on our new Zumos, and thank you to all our customers for helping us get to 200k orders.
This new stepper motor bracket is designed to work with typical NEMA 14-size stepper motors, including all of the NEMA 14 stepper motors we carry. It is made from 2mm-thick black anodized aluminum, and like the larger NEMA 17 bracket we released earlier this year, it features slot cutouts to allow for a variety of mounting options.
For more information, see the product page.
We are now carrying the short-range Sharp GP2Y0A51SK0F Analog Distance Sensor. Like the GP2Y0D815Z0F we released a few months ago, this sensor has a maximum intended sensing range of 15 cm, but unlike that other sensor, this module tells you where the detected object is in its 2 cm to 15 cm range. Its close minimum sensing distance of 2 cm and high 60 Hz update rate make this a great choice for close-proximity range-finding, or the analog voltage output can be passed through a comparator to make an adjustable-threshold alternative to our digital Sharp distance sensors.
This sensor uses a 1.5 mm pitch JST ZH connector, which is different from the connectors on all the other Sharp sensors we carry. Unfortunately, this means it will not work with the JST PH cables we recommend for use with some of those other sensors. We are working on getting compatible cables, but in the interim, it is not too difficult (but not exactly easy) to solder wires directly to the output pins like in the picture on the right.
This sensor is also quite a bit smaller than most of the other analog Sharp sensors, so it will not work with our new brackets.
For more information, see the GP2Y0A51SK0F product page.
You can now find all of our sale details, including a full list of the sale items, on our Black Friday/Cyber Monday sale page. The first doorbuster deals go live in less than 12 hours!
Our annual Black Friday/Cyber Monday sale is less than a week away! We have put up some of the special offers on the Black Friday/Cyber Monday sale page. Stay tuned for more details!
We now have special extended, stackable female headers for the Raspberry Pi:
The 2×20 versions work with the Raspberry Pi Model B+ (and the just-released A+), while the 2×13 versions match the I/O header on the older Raspberry Pi Models A and B.
See our Raspberry Pi category for our full selection of Raspberry Pi accessories.
