Want to display a PNG file on a display attached to an Arduino or other microcontroller board? You’ll want to look at [Larry Bank]’s PNGdec, the Arduino-friendly PNG decoder library which makes it much easier to work with PNG files on your chosen microcontroller. The PNG image format supports useful features like lossless compression, and was generally […]

One way of communicating with autistic and non-verbal people is through the use of a Picture Exchange Communication System or PECS board, which they can use to point out what they need or want throughout the day. However, the commercial versions of these boards have their share of problems — they’re expensive, and they’re fairly

Looking for a digital recreation of the classic analog volume unit (VU) meter? If you’ve got an Arduino, a few passive components, and a SSD1306 OLED, then [mircemk] might have the answer for you. As you can see in the video below, his code turns a handful of cheap parts into an attractive and functional audio
ANALOG STYLE VU METER WITH ARDUINO AND OLED DISPLAY Continue Reading
Art is a conversation, yes. But normally, it’s a short one: the artist makes a statement and the audience responds, each bringing their own interpretations. The hard thing about being an artist is that once you release a piece into the world, it’s sort of bound and gagged in that it can’t defend itself from

If you have a pile of USB cables this handy Arduino Cable Tracer project can help you test and diagnose your USB cables from issues, making sure you have the most efficient and safest possible system charging your mobile devices and gadgets. The project has been built by the team over at TechKiwiGadgets and allows you to
Test your USB cables for faults using the Arduino Cable Tracer Continue Reading
We’ll admit we are suckers for clock projects, and the more unusual, the better. We liked the look of [Peter Balch’s] astronomical clock, especially since it was handcrafted and was a relatively simple mechanism. [Peter] admits that it looks like an astronomical clock, but it isn’t the same as a complex instrument from medieval times. Instead,

On a recent rainy afternoon, [Thanassis Tsiodras] decided to build his own Forth for the Arduino to relieve the boredom. One week of intense hacking later, he called it done and released his project as MiniForth on GitHub. [Thanassis] says he was inspired by our series of Forth articles from a few years back, and his goal was to build

If you are considering purchasing a Nixie tube clock kit you may be interested in a new Arduino project published by Doug Domke to the Hackster.io website this week providing full instructions on how you can build your very own. Nixie tube clock build has been classed as an intermediate project and should take approximately

The inner machinations of the mind of cryptocurrency markets are an enigma. Even traditional stock markets often seem to behave at random, to the point that several economists seriously suggest that various non-human animals might outperform one market or another just by random chance alone. The classic example is a monkey picking stocks at random,

Machine learning is an incredible tool for conservation research, especially for scenarios like long term observation, and sifting through massive amounts of data. While the average Hackaday reader might not be able to take part in data gathering in an isolated wilderness somewhere, we are all surrounded by bird life. Using an Arduino Nano 33
