Arduino port expander spi

Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world. The project's products are distributed as open-source hardware and software, which are licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL),[1] permitting the manufacture of Arduino boards and software distribution by anyone. Arduino boards are available commercially in preassembled form, or as do-it-yourself (DIY) kits.

Similar to eBay, sellers on Aliexpress can be either companies or individuals. Aliexpress is different to Amazon because it acts only as an e-commerce platform and doesn’t sell products directly to consumers.

Automated Staircase RGB LED Lights
Automated Staircase RGB LED Lights


My staircase has claimed a broken toe some time ago. Fortunately, it wasn’t my toe, but I feel for the poor fella. The toe is OK now, but it got me thinking, is there anything I could do to reduce the risk of dealing with another victim? Plus if I could do this on the cheap, that would be super!

I Let Everyone on the Internet Control My X-Mas Decoration


Control any of the 55 RGB LEDs on the tree, let Santa twerk for you, control a model railroad, or display custom text on an LED dot matrix.
Have you always wanted anyone in the world to be able to control your X-mas decoration in your living room? - No? - We neither, but we built it anyway.

Digital & Binary Clock In 8 Digits x 7 Segments LED Display


This is my upgraded version of a Digital & Binary Clock using an 8 Digit x 7 Segment LED Display.
I like to give new features for usual devices, specially clocks, and in this case the use of 7 Seg display for Binary Clock is unconventional and it is an interesting and a different way of applying it.

Arduino Strain Relief Enclosure
Arduino Strain Relief Enclosure


Arduino boards are great for experimentation. You just plug the wires in, and the connections stay there with spring force. On the other hand, they also pull out quite easily, so I developed an Arduino Uno enclosure that when the lid is tightened, it also tightens down the wires going into the board, locking them down and providing a good amount of strain relief.
