The droid scoots around on what appears to be one large wheel, which conceals the Arduino boards as well as other electronics, batteries, and mechanical components. Denton’s wheel design is a bit more complicated mechanically than it first appears, as its split into a center section, with thin drive wheels on the side that enable differential steering.
On top, a cone-shaped head provides sounds and movement, giving the little RC D-O a ton of personality. The droid isn’t quite finished as of the video below, but given how well it works there, the end product should be amazing!
Mastermind is a game where one player attempts to guess a secret combination of colored pegs. It normally requires a second player to act as the judge, giving hints in the form of secondary pegs as to whether the other participant is on the right track. Maker “luisdel” decided to put a new spin on things using an Arduino Mega to display RGB LEDs on a Star Wars-themed play field. This automation allows players to directly compete, rather than taking turns.
In action, each player uses a series of buttons to enter light codes, with 10 tries at guessing the correct combination. No human judge is needed, so it’s a race to see who can unlock this critical sequence first and save—or further subjugate—the galaxy!
These are adverse times for rebellion. Although the Death Star has been destroyed, the Imperial troops are using free hardware and Arduino as a secret weapon.
That is the advantage of free technologies, any person (either good or bad) can use them.
In a hidden base located on the planet Anoat, they are building a 3D printer capable of replicating Imperial Destroyer.
The only solution to defeat the Empire is that a group of rebels commanded by Luke Skycuartielles and Obi-Wan Banzi, defeat the imperial troops and get the key that will give access to the plans to destroy the secret weapon.
This key consists of 4 colors and you have 10 attempts to get it deciphered. There are only four rules:
1. The colors can be repeated
2. A white light indicates that you have hit the right color and position
3. A violet light indicates that you have hit the color but not the position
4. If there is no light you have not guessed the color or the position.
You must hurry since at the other extreme, the evil Darth Ballmer will try to get the key before you. In that case, you will not be able to find out what it is and you will not have access to the plans of the secret weapon. Your mission will have failed.
Little Padawan, may the force accompany you to decipher the key and thus be able to save the galaxy.
South Korean LEGO Certified Professional Wani Kim, with the help of Olive Seon, has created an incredible replica of the Death Star Trench Run scene from Star Wars: Episode IV – A New Hope.
The LEGO diorama—which measures 2,680mm (8.79 feet) long, 1,370 mm (4.49 feet) deep, and stands 1,100 mm (3.60 feet) tall— features defensive turrets, along with Luke’s X-Wing, the wreckage of another Rebel ship, and Vader and two TIE Fighters in pursuit.
The build required 80,000 LEGO bricks to complete and even includes a cutaway of the back, revealing the insides of this astronomical object. If that wasn’t enough, an Arduino was used to coordinate flashing effects to further enhance this iconic recreation.
Additional images of this impressive project, plus some of Kim’s other work, can be found on his Instagram page.
In several iterations of the Star Wars saga, small black droids can be seen scurrying around imperial installations. While they tend to fade into the background or provide a fun distraction in the movies, the mouse droid by Potent Printables acts as a sort of physical messaging app. It’s able to travel to the correct location, then pop open to unveil a scrolling LED sign.
Potent Printables can trigger the side door using a Bluetooth app on his phone. On command, an RC servo pushes it open, and lowers it down using a stepper motor/reel setup. An Arduino Uno along with an Adafruit Motor Shield are used for control, while an HC-05 module enables communication with the system.

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, the project has also been approved by Lucasfilm, the studio behind the saga, allowing Clavijo to bring it to official Star Wars events all over the world.
When not recreating Star Wars characters, Clavijo spends his days working as an engineer and has designed controls for “clean rooms” using Arduino Uno. You can see his design–made with CATIA–on Thingiverse.
Strong is the Force, with this Padawan. To coincide with the latest installment of the continuing saga from a galaxy far, far away, [Rohit Gupta] built a Star-Wars themed interactive doormat. The doormat detects a footstep using capacitive sensing and plays a random Star Wars audio clip like the opening theme or the Imperial March or a famous phrase from the movie. Check out the video below the break.
The current setup is temporarily breadboarded, but we are sure it will be popular enough with his visitors to make him tidy it up. The hardware consists of an Arduino with an audio shield connected to a pair of speakers. A capacitive wire loop under the mat and a capacitive sensor tuned to the mat size wire take care of the sensing.
When Earth people step on the mat, the sensor triggers the Arduino to play a random audio clip from the SD card. The capacitive sensing is taken care by the TP223 1-key touch pad detector chip (PDF), which he mounted on a home etched board with SMD parts. The whole bundle is powered by a small “power bank” battery pack like the ones used to charge mobile phones.
Dave Stein is a software engineer during the day and a tinkerer on Arduino projects in his free time after work. He submitted on the blog his first Arduino project with the goal of powering his old AT-AT Walker toy (mid 1980s) with Arduino Uno and make it walk and perform some of the functions we see in the Star Wars movies.
AT-AT (All Terrain Armored Transport) are four-legged combat walkers 22.5mt (73.8ft) tall of the Galactic Empire, one of its most famous military symbols introduced in “Star Wars V: The Empire strikes back”, and we may see them again in the next weeks on “Star Wars: The Force Awakens” the upcoming episode of the saga opening December 18th.
The AT-AT walker toy updated by Dave is controlled by a wired Xbox 360 controller that interfaces with a computer and transports a signal to the Arduino Uno for walker movement:
The left and right triggers move the walker forward and backward while the right stick moves the head horizontally. If you have ever played with this toy you may remember it was clumsy and difficult to move. In my project I wanted to learn about and conquer the difficulties of quadrupedal movement. The realization process for my project involved a massive amount of trial and error, research, and failures. I have to say that I failed many more times than I succeeded with configuring the servos with the Arduino. I went down many long roads to learn about prototyping with the breadboard, soldering, and redesigns of the final product. The most difficult part of the project aside from adjusting the gait of the walker for balance and movement was providing enough power to the servos without frying the microcontroller or any of the components. I was finally able to overcome these difficulties by implementing the Adafruit servo shield.
