When you buy—or even salvage—limit switches for electronics projects, you expect them to work again and again, producing normally open (NO) and normally closed (NC) signals as needed. Generally, they do work quite well, but if you want to test things for a little extra assurance, you might want to check out this project by […]
If you need to fill a bunch of water bottles, you could do so using your hands and a sink… or you could automate the task like YouTuber Easy HomeMade Projects. The build is controlled by an Arduino, spinning a carousel of a half-dozen bottles under a fill hose with a stepper motor and timing belt. […]
If you wear a CPAP (Continuous Positive Airway Pressure) mask to treat obstructive sleep apnea, you may wake up to find that you’ve flung the mask off during the night or adjusted it to the point that there’s a large air leak. To help with this problem, Bin Sun has developed a CPAP monitor that […]
While members of the Oshman Engineering Design Kitchen makerspace at Rice University generally do a good job with wearing proper eye protection and gloves, hearing safety has lagged behind. In order to make it obvious when students need to apply the protective equipment, the “Ring the Decibels” team there has come up with an excellent […]
LEDs are fun, and RGB(W)s adds a new element to things, but what if you want a light that can also move by itself? The Mover3D does just that as a pan/tilt system controlled by the DMX512 communication protocol. You simply feed instructions in via any standard lighting console, and it dances around under your […]
The wait is finally over, the Arduino Nano 33 BLE and BLE Sense are both available. The boards have been manufactured, delivered to our warehouses, and will start shipping in mid-August. These new boards are an exciting addition to our product line — based on the powerful Nordic nRF52840 Bluetooth SoC, a Cortex-M4F Arm processor […]
This post is from Martino Facchin, who is in charge of the firmware development team at Arduino. Hopefully this is the first of a series of posts describing the inner workings of what we do. The new, shiny and tiny Nano 33 BLE and Nano 33 BLE Sense are on their way to becoming a […]
It’s easy to see that painting takes a lot of skill, but few really understand how much skill is involved like John Opsahl, who created the “If Then Paint” CNC canvas painting machine. In order to produce the proper paint strokes, his device implements full six-axis brush control, moving not only in the X/Y/Z coordinate system, […]
Richard J. Prinz wasn’t satisfied with pickable physical locks, so he decided to see if he could instead secure physical things with his YubiKey USB security fob. His setup uses an Arduino Uno, along with a USB host shield, to read data from the YubiKey then compare it to a stored password or passwords. If […]
We are excited to announce that we’ve selected Auth0 as the identity management platform of choice for Arduino. We will replace our own Single Sign On solution with Auth0 for all public facing web properties, including Arduino Create and other apps. We discovered that our own homegrown authentication solution would not scale to meet the […]
