When Geert Wanten’s wife got tired of opening up the chicken coop to let them out in the morning, he decided to automate the situation using an Arduino Nano. Wanten’s DIY system calculates the sunup/sundown via info from a DS1307 RTC module, pulling the door up with a gearmotor and a spool of fishing line. […]
This post was written by Valentina Chinnici, Arduino Product Manager. Arduino and Google are excited to announce that the Science Journal app will be transferring from Google to Arduino this September! Arduino’s existing experience with the Science Journal and a long-standing commitment to open source and hands-on science has been crucial to the transfer ownership […]
Imaging phantoms are used to evaluate and test medical devices, such as X-ray machinery, where a human subject would be impractical and/or dangerous. In order to simulate the motion and deformation of a lung, Stefan Grimm created an Arduino-powered phantom at a materials cost of around $350 USD. Much of the project’s structure is printed […]
Clocks normally tell you the time in your particular location, but what about that person that you know across the country or even on the other side the world? What time is it there? While it’s easy enough to do a web search or do a calculation, in order to find this out at an […]
As a part of their masters program at the University of Stuttgart, Jan Ingo Haller and Lorin Samija created a robotic pet that moves in a manner that may not be immediately evident. With the internals obscured by a cloth covering, the moving OLOID, or mOLOID, seems to roll from one vague lobe section to another […]
PeterQuinn925 swims for exercise, and to train for the occasional triathlon, but when doing so he often zones out and forgets how many laps he has swam. To solve this problem without spending a lot of money on a commercial solution, he created his own counter using an Arduino Nano and an ultrasonic sensor. The sensor detects […]
While 2020 may seem like a very futuristic year, we still don’t have robotic maids like the Jetsons’ Rosie the Robot. For his latest element14 Presents project, DJ Harrigan decided to create such a bot as a sort of animatronic character, using an ESP8266 board for interface and overall control, and a MKR ZERO to play stored […]
While many of us take playing tunes for granted, whether via MP3s, CDs, or streaming services, for others — such as many that are very young or old — actually figuring out the interface can be a challenge. To make it easier for the elderly (and children) to enjoy music, Ananords and his girlfriend created […]
If you participate in beer pong, and your skills aren’t up to the challenge, you might be in for a rough time. While “practice makes perfect,” if you’d rather shortcut this process then engineers Nils Opgenorth and Grant Galloway have just the solution with their Arduino-powered PongMate CyberCannon Mark III. This wrist-mounted launcher uses a […]
It’s generally not advisable to leave equipment running when unattended. As a safeguard against this possibility at hackerspaces and elsewhere, element14 Presents’ Dave Darko built a custom switch that requires users to intermittently push a button in order to produce additional ‘on’ time. The trick here is that instead of having one keep-alive button, the unit has […]
