When you see a mechanical clock, you know on some level that it took a vast amount of expertise and craftsmanship to get working, but you might also assume that this could all be swapped out very easily with modern electronics. While this might be the case with a clock that only tells time, as David […]
Sequencers, as YouTuber “LOOK MUM NO COMPUTER” explains, are musical devices that go through a sequence of tones one by one. While this can be done quite simply with a 4017 counter chip, if you instead substitute in an Arduino board for the counter, you can make your gadget behave normally, go backwards, or even act as a […]
Have you ever wanted a vending machine for snacks but didn’t know where to start? With an Arduino Mega, some motors, and an infrared sensor to detect coins, Dejan Nedelkovski decided to build his own using only hand tools. The DIY vending machine’s structure is made out of MDF, and uses wires bent into helical shapes to twist items […]
If you want to make your own custom PCBs at home, one method is to paint a circuit board blank with photosensitive material, then expose the portion you don’t want to UV light using a printed transparency. After a process of etching and stripping, the correct traces are generated. As seen here, in order to […]
Quiz games, where contestants try to “buzz” in and answer questions make for fun televised game shows, but they can also be great for making learning fun. In order to avoid paying several hundred dollars for an official quiz machine, Instructables user “arpruss” decided to build one for his school using an Arduino Mega. The […]
Alejandro Clavijo, together with his father Jerónimo, spent two years building the first official fan-made model of the R4-P17 Star Wars droid. For those not familiar with this family of droids, R4-P17 was the robot companion to the young Obi-Wan Kenobi. The replica is made of aluminum and wood, and runs on four Arduino boards. Impressively, […]
![Desafío STEM + Arduino Podcast [Español]](https://blog.arduino.cc/wp-content/uploads/2017/11/podcast-telefonica-blog-2-copy.jpg)
Con el fin de apoyar a los nuevos participantes del Desafío STEM 2017, Arduino y Telefónica se han unido para crear una serie de tres podcast, abiertos al público en general, conducidos por David Cuartielles. Desafío STEM es un concurso interescolar que fomenta el desarrollo de competencias tecnológicas, creado por Telefónica Educación Digital para impulsar […]
Strandbeests, as originally conceived, are gigantic PVC creatures that walk across the sand under wind power. While building one is certainly an enormous undertaking, smaller models are available that let you experience this strange kinetic motion in a more approachable size. These are also normally propelled by moving air, but maker “ArduinoDeXXX” decided to take […]
UPDATE: Thank you for all those who applied. Our call for volunteers is now closed. See you in Rome! Planning on attending Maker Faire Rome next month? We’re currently seeking volunteers to join our team during the event—staffing tables and displays, leading one-on-one workshops and demos, and providing technical assistance when necessary. If you volunteer with us for one […]
As outlined in this Circuit Digest write-up, with the right hardware, you can now control your computer using hand gestures. While interesting, this kind of technology can be a little expensive. But if you’d like to augment your notebook or laptop via simple gesture capabilities without breaking the bank, B. Aswinth Raj has your answer in the […]
