Adnan.R.Khan recently decided to give his room’s sliding door latch an upgrade by designing a mechanism to open and close it, using little more than an Arduino Uno and Bluetooth module.
His automated device is operated via a smartphone app written in MIT App Inventor, and it employs a shield to control a small DC motor. The motor then pulls a cable wrapped around two pulleys in order to move the simple barrel latch in or out.
It’s an amazing display of what can be done with parts at hand and basic tools, and could certainly inspire other home security hacks. Be sure to check out the build process and the setup in action below!
Using an Arduino Nano 33 IoT, Jithin Sanal designed a home monitoring system capable of detecting noxious gases with an MQ2 sensor as well as sensing temperature, pressure, humidity, and ambient light via a BME280 sensor and an LDR. All of this is mounted onto a custom PCB that’s powered by a 9V battery, or one could also use a 9-12V adapter if more convenient.
Data is passed on to Ubidots over WiFi, which provides a configurable dashboard for viewing the readings anywhere in the world. The system can also send notifications via SMS, email, or Telegram to let you know if anything is awry.

In his latest video, Will Cogley has created an animatronic heart so realistic that you might wonder if it’s the actual thing.
The device is made out of molded silicon with fake blood poured on top to enhance the effect, and inside a trio of servo motors push the lower and upper sections of the prop out in a very lifelike pattern.
Control is via an Arduino Micro along with an I2C servo controller, while power is provided by an external tether. A potentiometer on the back is used to vary heartbeat speed.
He also made a simpler — and less potentially terrifying — version with a cloth exterior. This one is battery-operated and runs on a motor and linkage system, perhaps making it good for a nice portable joke!
Child-sized wheelchairs can be difficult to come by, and unfortunately aren’t as much fun as something like a ride-on car. The South Eugene Robotics Team, or FRC2521, decided to address both challenges by building a mini Jeep augmented for kids with limited mobility.
Instructions found here detail how to modify the battery-powered toy, including what can be recycled and what extra parts will need to be purchased. In the new configuration, the Jeep’s two rear motors are configured for differential control, with the input regulated by an Arduino Nano and a pair of electronic speed controllers (ESCs).
In this project, a joystick replaces the original pedal and steering wheel, and it looks like a lot of fun when implemented in the similarly-outfitted firetruck below.
Model cars can be fun to use and look at, but when driving one it’s difficult to get the same sort of movement in the suspension as a full-sized vehicle. To enhance his 65cm long 8.5:1 Oldsmobile Dynamic 88, creator Dimitar Tilev turned to an active suspension system controlled by four micro servo motors.
When maneuvering the little beast, an Arduino board along with an MPU-6050 IMU allow it to raise and lower each wheel individually based on the forces it experiences, giving an amazing approximation of an actual car’s behavior.
The build also features a sound effects system to simulate engine noises and exhaust pops, and an attention to detail in the styling that sets it apart as something really special.
We’re kicking off this year’s CES with some big news.
Millions of users and thousands of companies across the world already use Arduino as an innovation platform, which is why we have drawn on this experience to enable enterprises to quickly and securely connect remote sensors to business logic within one simple IoT application development platform: a new solution for professionals in traditional sectors aspiring for digital transformation through IoT.
Combining a low-code application development platform with modular hardware makes tangible results possible in just one day. This means companies can build, measure, and iterate without expensive consultants or lengthy integration projects.
Built on ARM Pelion technology, the latest generation of Arduino solutions brings users simplicity of integration and a scalable, secure, professionally supported service.
“By combining the power and flexibility of our production ready IoT hardware with our secure, scalable and easy to integrate cloud services we are putting in the hands of our customers something really disruptive,” commented Arduino CEO Fabio Violante. “Among the millions of Arduino customers, we’ve even seen numerous businesses transform from traditional ‘one off’ selling to subscription-based service models, creating new IoT-based revenue streams with Arduino as the enabler. The availability of a huge community of developers with Arduino skills is also an important plus and gives them the confidence to invest in our technology”.
But that’s not all. At CES 2020, we are also excited to announce the powerful, low-power new Arduino Portenta family. Designed for demanding industrial applications, AI edge processing and robotics, it features a new standard for open high-density interconnect to support advanced peripherals. The first member of the family is the Arduino Portenta H7 module – a dual-core Arm Cortex-M7 and Cortex-M4 running at 480MHz and 240MHz, respectively, with industrial temperature-range (-40 to 85°C) components. The Portenta H7 is capable of running Arduino code, Python and JavaScript, making it accessible to an even broader audience of developers.
The new Arduino Portenta H7 is now available for pre-order on the Arduino online store, with an estimated delivery date of late February 2020.
If your robotic vehicle will only work on smooth surfaces, the choice of a wheel is obvious. For more rugged bots, the same applies with knobby wheels. For those that need to operate in both environments, however, the Adaptive Field Robot presents a new solution in the form of wheels that actually change dynamically depending on the terrain.
This Arduino-powered robot is able to transform its two driving wheels from a nearly circular shape into a claw-like arrangement using secondary motors that rotate along with the wheel assembly.
When the bot detects a difference in terrain via an ultrasonic sensor, the motors springs into action, activating a rack-and-pinion system that expands the two halves of the wheel into “claw mode.”
Be sure to check out this innovative robot in the video below, including some trial-and-error during the development process.
If you need another idea for how to creatively diffuse LED lighting, then look no further than the “Light Me Up!” project by Hyewon Shin, Eunjeong Ko, and Junsung Yi.
Their setup uses 312 3D-printed and laser-cut light triangles, each of which contains a trio of RGB LEDs. Users select the desired light by pressing the triangles themselves, via buttons concealed beneath the main assembly. Several Arduino boards are used to control the massive structure.
With such an involved triangular display, a number of interesting 3D-like shapes and even words can be created by users. Alternatively, smaller triangle arrangements can also be constructed using the same build concepts.
This project has several triangles that form a hexagonal shape. So you can create stereoscopic patterns according to how you design light! Just press each piece and various colors will be gradated, and when the color you want comes out, just hit the hand you pressed and it will continue to shine beautifully with the color you wanted!
Check out its triangular luminescence in the videos below!
When you need to test a single servo, it’s a fairly straightforward task. Just hook it up to an Arduino to generate the proper PWM signal, along with an appropriate power supply, and you’re in business. If, however, you need to test a bunch of them at the same time, things get a bit more complicated.
To solve this challenge for another project he’s working on, Will Cogley built a 3D-printed tester capable of experimenting with 16 servos at the same time.
The device runs on an Uno, and uses four potentiometers and two buttons for controlling the motors in sets of four. Settings from all 16 outputs are displayed on a 1.8” TFT screen and an Adafruit 16-channel driver is implemented to interface with the servos directly.
