  • Deep dive into how the Teensy microcontroller interacts with the Arduino library



    Pin configuration is more complex than you might expect. The problem is that the processor chip has 144 pins (in a 12×12 grid), but the microcontroller provides a much larger number of functions. The solution is that each pin has up to 8 different multiplexed functions, and you can select one of these functions for each pin. Thus, you can't use all the features of the chip at the same time, but hopefully you can use the features you need.


  • PUPPI is a tinyML device designed to interpret your dog's mood via sound analysis | Arduino Blog

    Dogs are not known to be the most advanced communicators, so figuring out what they want based on a few noises and pleading looks can be tough. This problem is what inspired a team of developers to come up with PUPPI — a small device that utilizes tinyML to interpret your canine companion’s mood through vocal signals. Their project employs an Arduino Nano 33 BLE Sense and its onboard microphone to both capture the data and run inferencing with the model they trained using Edge Impulse. After collecting ample amounts of data for barks, growls, whines, and other noises, their model achieved an accuracy of around 92%.

  • Homemade mechanical color TV runs on an Arduino Due | Arduino Blog

    Nearly everyone alive today has never the technical marvel that is the mechanical television. In short, the work by quickly strobing a light through a disc that has holes cut around its perimeter, with each hole being slightly lower than its predecessor. Combined with the persistence of vision effect, this gives the illusion of a still image with its number of rows being equal to the number of holes in the disc. YouTuber “Science ‘n’ Stuff” wanted to try creating a modern version that uses a microcontroller to precisely adjust an LED’s color, rather than using an analog signal.

    The device has a single large plastic disc with 32 holes for a total of 32 rows in the image. It’s spun at 1500 RPM by a DC motor that’s driven via PWM, and because there can be some variance in the motor’s speed, the synchronization signal that’s produced on each full rotation is also used to carefully adjust the motor’s speed to keep it constant. Both images and sound are read from an onboard microSD card, with the images being converted into pulses of light and the sound being played on a mono speaker. All of this is controlled by an Arduino Due board.

  • This Arduino device will sort your M&M's by color | Arduino Blog

    If you were challenged to design a device that could sort M&M candies by color, how would you make it work? You might consider using machine learning, which has become accessible in recent years. There are even ML models available today that can run on Arduino boards. But Jack Monaco (AKA Jackofalltrades_) found a more elegant solution when he created this Arduino Uno-controlled M&M’s sorter.

    We perceive color based on the wavelengths of light that an object reflects. A white object reflects all visible wavelengths well. A black object doesn’t reflect any visible wavelengths well. A blue object reflects blue wavelengths better than others. This machine relies on those facts to detect the color of an M&M candy.

  • RC skateboard moves in any direction | Arduino Blog

    Skateboards are great for going in a straight line, or gently curving one way or the other, but Proto G Engineering’s “omnidirectional board” takes things to a whole new level. Thanks to four 3D-printed Mecanum-style hub wheels, this device can not only move forwards and backwards, but can slide left and right and even spin like a tank!

    The system is powerful enough for human riders, but currently has some issues carrying such a load at low speeds, making it a mostly unmanned vehicle for the time being. Steering is handled by a remote control unit while a GoPro camera setup provides a first-person view. An Arduino Nano is implemented on each of the hub motors to translate RC PWM signals into the proper driver format. The Nanos also control the forward/reverse/brake pin input on the motor drivers, making this unique board possible.

  • Turn your bicycle into a Pokebike with DJ Harrigan's MKR Zero device | Arduino Blog

    Within the Pokemon series there exists a special bicycle that plays a little tune when ridden, and this is what element14 Presents’ DJ Harrigan was trying to recreate with his DIY Pokebike project. It has a simple purpose: play a song and increase its volume while accelerating and then decrease the volume and eventually stop playing it once the bike comes to a halt.

    The circuit uses an Arduino MKR Zero to handle all of the inputs and outputs, and with an onboard microSD card slot and the ability to output digital I2S audio, playing music is easy. Speed is determined by a Hall effect sensor and magnet pair that sends a pulse whenever the wheel has made a rotation. By tracking how many rotations have been made in a second and seeing the changes between these values, acceleration can be derived.

    Harrigan then designed and 3D-printed a simple enclosure that houses all of the circuitry, including a battery pack. The front is shaped like a Pokeball, and it has an illuminated push button that allows for the user to interact with it. Finally, there’s a small speaker at the back connected to an I2S amplifier that takes signals from the MKR Zero and converts them into sound.

  • The Piano Metronome is key to keeping the beat | Arduino Blog

    In the world of music, being able to keep time accurately is vital when playing a piece, as even small deviations in timing can cause the notes played to sound “off.” Ordinarily a device called a metronome is used to provide consistent ticks that the musician can use, but most are not that visually interesting. This is what inspired ChristineNZ over on Instructables to create her own metronome that uses an Arduino Uno to both show the beat and produce a small noise.

    ChristineNZ’s Piano Metronome enables users to select both the rate (tempo) of the beat and its volume by turning one of two rotary encoders. Rather than having some clunky interface, this project has a large 20×4 I2C LCD on the front that displays the current time via an RTC, the sound’s amplitude, and even subdivisions. The top of the enclosure also holds four RGB LEDs that visually indicate the beat and subdivision if present.

  • Raspberry Pi 400 review: The keyboard is the computer [Ed: Reviews by Microsoft operative Simon Bisson, who hates GNU/Linux]

    The heart of the Raspberry Pi Foundation's mission is to bring computing to everyone, wherever they may be. The single-board Raspberry Pi devices have gone a long way to delivering on that promise, via kits that bundle keyboard and mouse for a full computing experience.

    But what if the Pi was built into the keyboard? After all, there have been many projects that put these devices inside laptop cases or built them into media centres, or storage systems. But those have all been third-party projects, taking off-the-shelf Raspberry Pi devices and adding them to new hardware. What if the boards could be redesigned, and integrated into, say, the official Pi keyboard?

    The tiny Arm Linux board comes with up to 4GB RAM, 16GB eMMC flash, and either AP6212 or AP6256 wireless module. plus all interfaces from Raspberry Pi Zero W, but with a twist as the mini HDMI port is replaced by a micro HDMI port, and USB-C ports are used instead of micro USB ports.

  • Tiny Radxa Zero SBC runs Armbian on Amlogic S905Y2

    Radxa’s Raspberry Pi Zero-like “Radxa Zero” SBC runs on Amlogic’s quad -A53 S905Y2 and sells for $15 (512MB LPDDR4) to $45 (4GB with 16GB eMMC). Features include WiFi/BT, 4K-ready micro-HDMI, 40-pin GPIO, and 2x USB Type-C.

    The Raspberry Pi Compute Module series has followed mainstream Pi SBCs into Cortex-A53 and Cortex-A72 territory with the RPi CM3/CM3+ and CM4. Yet, the slightly larger and more SBC-like Raspberry Pi Zero and WiFi/BT enabled Raspberry Pi Zero W are still stuck with a 1GHz, ARM11-based Broadcom BCM2836. They nevertheless remain popular due to their $5 price, 65 x 30mm dimensions, and support for Raspberry Pi HATs and most Pi software.

  • The Crumble Deck is a Stream Deck alternative based on an Arduino Due | Arduino Blog

    Stream Decks have gained a great deal of popularity within recent years. However, increased demand and a limited supply of them has caused their prices to skyrocket and availability to dwindle, leading many to seek alternatives. The streamer known as CoCoaCoCi has created a DIY Stream Deck before, but this first iteration only had a 3.5” touchscreen that wouldn’t always pick up inputs. So, for his next project, CoCoaCoCi wanted to have some physical buttons along with a display that would only be used to navigate menus and actions.

    He started by quickly designing and 3D printing a case to house the Crumble Deck’s electronics, including an Arduino Due as the main processor, a 3.5” TFT LCD screen, and 20 buttons. All the buttons were wired together in a matrix that reduces the number of GPIO pins required to detect them. His code then polls each column and row to check which button is currently being pressed.

  • This archery robot always hits the target | Arduino Blog

    Both archery and robotics are extremely fun, but what happens when you combine the two? In Kamal Carter’s case, he constructed his own autonomous robotic archery system that can not only acquire and aim at targets, but even draw back the bow and fire an arrow all on its own.

    The project features an Intel RealSense Depth Camera at its heart to acquire targets by looking for abnormally bright colors and to compute its distance away from them. This information is then fed to an Arduino Mega that uses some simple physics to determine where exactly the bow should be aimed via a pair of stepper motors. Once the target has been dialed in, another stepper pulls back the bow while a servo releases the string’s tension, thus firing the arrow.
