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), 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.

Yes, you read the title correct. Have you ever forgot your birthday, that you need someone else to remind you about it ? Or what if you can gift to someone you love, a device that\'ll wish them on their birthday for 50 times ?
This project started as part of my Halloween costume, and then expanded...a lot. I ended up making two lightsabers - a Kylo Ren style saber and a Rey / Anakin Skywalker style saber, and creating different Arduino code to simulate each. And, I decided to go beyond the normal lightsaber, and create a party mode with colorful animations on the saber.
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.
In my heart I know we are stuck with the QWERTY keyboard but that doesn’t stop me wanting something different. I have thought about switching to Dvorak or Colemak key assignments but don’t want to deal with the problem of mental interference when I have to switch back to a normal keyboard.
It turns out that it is quite easy to get Alexa communicate with Arduino via Raspberry Pi with Node-RED. All you have to do is installing two Node-RED modules and setup up a Node-RED Flow with Alexa Local and Arduino nodes. Here I have a project which has Alexa turn on and off two LED lights as a demo.

If you\'re like me, then you have a small pile of clothes on the floor that may or may not be dirty. This could include jeans, dress shirts, and barely worn shorts. So how can you tell which clothes are clean or dirty? I came up with a way to track various articles of clothing using NFC and a Raspberry Pi.
