ABC: Basic Connections – The Essential Book for Makers

Arduino is the world’s most popular open-source electronics tool, used every day by millions of people for experimenting and learning electronics. Thanks to the support of the maker community, anyone can share their knowledge and learn from thousands of other projects. You can create anything using basic components like switches and LEDs, or more advance components like digital interfaces and wireless commu ...

A LASER CUT GINGERBREAD CATHEDRAL

One of the more disappointing news stories of 2019 was the fire at the Notre Dame cathedral. Widely considered a building of great historical importance and architectural merit, it was heavily damaged and will take significant time and resources to repair. Fundamentally though, if you’re reading this, that’s probably someone else’s job. Instead, why not just build your own Notre Dame out of gingerbread at h ...

Arduino Parking Assistant

Those of us who have small garages know the frustration of parking a little bit too far in or a little too far out and not being able to walk around the vehicle. We recently bought a larger vehicle, and it has to be parked perfectly in the garage to walk around the front and back. To appease my frustration I decided to design a device that would allow me to park in the exact spot every time. I love working ...

The New Light-responsive Nano LEDs

A team of researchers from the US and South Korea reported a unique type of NanoLEDs with unprecedented brightness levels, that excess 80,000 cd/m2, and also can operate both as light emitters and light detectors. These new LEDs are about 50nm long and 6nm in diameter. As described in the paper, they included quantum dots of two different types, one of which can enhance radiative re-combinations (useful for ...

Hack Your Car With Macchina M2

Car hacking applications have been growing during the last few years, making it faster and cheaper to get into automotive tinkering. A new device was launched recently on kickstarter called M2 by Macchina. M2 is an open-source, versatile development platform which can be wired under the hood for a more permanent installation or plugged into the OBD2 port, enabling you to do virtually anything with your vehi ...

GARDENING AS NATURE INTENDED, WITH AN ARDUINO

We’re not exactly what you’d call naturalists here at Hackaday, so to us, the idea that hot pepper seeds need to germinate in hot conditions sounds suspiciously like a joke. The sort of thing somebody might tell you right before they try to sell you an elevator pass, or cram you into a locker. But we don’t think [Dean] would have gone through so much trouble if it wasn’t true. You’re still not going to sell ...

“Chipiplexing” efficiently drives multiple LEDs using few microcontroller ports

Actual microcontrollers have powerful bidirectional I/O ports, and you can use different techniques to fully exploit such capabilities. Recent Design Ideas described the “Charlieplexing” method as an effective way to drive M=N×(N–1) LEDs using only N bidirectional I/O ports and N resistors (reference 1 and reference 2). Unfortunately, using Charlieplexing allows you to drive only one LED at a time, so, when ...

PcbDraw – KiCAD board into a nice looking 2D drawing

This small Python script takes a KiCAD board (.kicad_pcb file) and produces a 2D nice looking drawing of the board as an SVG file. This allows you to quickly and automatically create awesome pinout diagrams for your project. These diagrams are much easier to read than a labeled photo of a physical board or an actual KiCAD design. You and your users will love them! Dependencies This script requires the pcbne ...

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 a LED dot matrix. Story Ooooops.. I think I made a mistake and accidentally posted the project twice, on "Arduino Create" AND "Hackster.io". Please visit: this site to read about our crazy idea. Sorry! ---------------------------------------------------------------------------------- Have ...
