Japanese YouTuber Mutekimaru Channel set up a fishtank to play Pokemon. A camera tracks the fish’s position in the tank to indicate controller inputs. The video above goes through the whole set up. After one unfortunate game crash the fish actually end up making an eShop purchase and revealing the credit card info!

More from Sora News:

Pokémon Scarlet and Violet are the newest paired games in the Pokémon franchise, and so there are a lot of YouTubers streaming gameplay of them these days. What sets Mutekimaru Channel’s Pokémon Violet stream apart, though, is that it’s played by fish.

In short, the system allows the fish to use the system’s controller, even without directly touching it. However, the unexpected side effect of that is that this allows the fish to use the controller for non-gameplay functions too, which led to an absolutely crazy chain of events

The Infineon team recently create their own version of this mechanical 7 segment display. It is a really fun project for a funky large scale clock or display!

In this video I’ll be showing you how to build your own two digit mechanical seven segment display using an Arduino Mega and micro servos. You’ll need an Arduino Mega as the Uno doesn’t have enough PWM pins to drive even a single digit mechanical seven segment display, it only has 6 PWM pins. The Arduino Mega has 15 PWM pins, enough to drive two digits. The digit segments are all 3D printed using bright green PLA.

Natasha wanted to make a lit-up animated Birthday cake. She turned to using NeoPixel color LEDs, inside the cake!!

What’s better than birthday candles? LED animations of course! In this video we’ll tackle the age old question: can you embed LEDs into a birthday cake? Using flexible LED matrixes and an Arduino, Natasha explores how to incorporate the matrixes into a cake and drapes fondant icing over them to diffuse the light. It’s an exciting use case for LEDs and a spectacular birthday cake!

The project uses an Arduino Nano 33 IoT to drive the animations, programmed using the Arduino IDE and the Adafruit GFX library. The NeoPixels are a flexible matrix and strand from Adafruit.

Tired of rummaging for your remote every time you get up from the couch? This Arduino project pauses and plays your TV automagically!

I’m often tired when I sit down to watch TV at the end of a day, so I want the experience to be as easy as possible. One simple improvement I’ve dreamt about is having the TV notice when I’ve got up so it can automatically pause the current show, and then resume it when I return. I decided to prototype this using one of our Person Sensors, together with a Circuit Playground Express board from Adafruit.

On the Adafruit Forums, user hydrophyte shares a fascinating project:

This is a phytoplankton culture setup in a wall-mount clear plastic cylinder with additional brackets holding electronics enclosures + air pump. This kind of affordable small air pump tends to wear out fast, so it runs just one minute per hour: probably adequate for occasional stirring of this easy phytoplankton culture.

Phytoplankton is the extreme halophile, Dunaliella salina. In good growing conditions, D. salina can produces lots of beta carotene pigment and tint the salty water with a bright orange or red coloration. I have seen this same culture glow with an amber-orange hue, but tonight it’s just plain green.

This is a simple setup just with an RTC, 7-segment clock and relay. I didn’t really need all the pins for this one, but I like using the Metro Mini very much. It runs just like a regular Uno and never gives me any trouble.

really like that white 7-segment clock display. It looks cool.

The RGB LED strip behind the clear tube can shine with many different colors. The white 1W LED at the top renders better phytoplankton coloration in photos.

An advantage of keeping this particular phytoplankton in this kind of low-maintenance setup is that the hypersaline conditions (more then twice as salty as seawater!) will tend to exclude Bacteria and other Algae that could otherwise contaminate and foul the culture.

Sebastian Tomczak has developed an Arduino sketch and Max patch which takes the inertia motion unit data of the Nano BLE 33 and sends it via Bluetooth BLE using the ArduinoBLE library.

The data is transferred as a set of BLE Characteristics as a BLE Service. The Max patch scans for the BLE device, connects to it and then subscribes to the data streams. The output can be normalised, smoothed and then routed via MIDI to music software such as Ableton. The Max patch uses the max-ble external.

With Bluetooth Low Energy (BLE), devices do not need to pair in order to communicate data. Instead, a paradigm of central and peripheral devices is used. Central devices scan for Peripheral devices and initiate connections. Peripheral devices advertise their BLE Services and wait for a Central device to connect. In this example, the computer running the Max patch is the Central and the Arduino Nano BLE 33 is the Peripheral.

A given Service on a Peripheral device is made up of one or more Characteristics. A Characteristic contains one or more bytes of data and may be part of a standard profile or a generic type with customised data length. Each Service and Characteristic has a UUID unique identifier that is either a 16-bit or 128-bit string. The Arduino BLE library contains a number of functions to create a BLE Service and Characteristic.

Arduino has partnered with Damien George to use MicroPython on a number of Arduino products.

Thanks to one of our developers (Ubi de Feo) we were able to test MicroPython on a class of students and we’ve learned a lot from that experience. In particular, we noticed that it’s hard to find a very simple cross platform MicroPython IDE that would be as easy to use as the original Arduino IDE.

Luckily we came across the work of Murilo Polese, who developed a simple tool we were able to adapt and use for teaching. The results have been so good that we decided to collaborate with him to produce a tool we can share with the community.

We’re very excited to announce the new Arduino Lab for MicroPython, a simple, cross-platform IDE for MicroPython that supports any board with a serial REPL interface so it can also work with non-Arduino boards.

This is not an official product yet, it’s an experimental tool — but we wanted people to play with it so we created a new website “Arduino Labs,” where we’ll post experimental tools for people to try out and give us feedback. It’s not guaranteed that they will become fully released products. In the meantime, enjoy them and try them out!

You can find Arduino Lab for MicroPython at labs.arduino.cc and download their initial software here.

HackSpace Magazine Issue 59 reviews the Metro Mini 328 V2:

Although Arduino-compatible boards are not as difficult to find in stock as a Raspberry Pi, they can still be challenging to source. The revamped Adafruit Metro Mini 328 V2 is a 5 V, 16MHz, Arduino-compatible board that fits right into the STEMMA QT and Qwiic Connect ecosystem. And is in stock.

The board still features the same ATmega328 integrated circuit, same pinout, same size, and same mounting hole locations. But, now you have the STEMMA port for prototyping without the need to solder. Just snap together and get programming. They also got rid of the old micro-USB port and upgraded to a reliable and more robust USB-C connection. It’s teeny, it’s tiny, it’s mini, and it’s Arduino-compatible! And it’s in stock! What’s not to love?

They give the board a 9/10, saying it’s “Updated and better than ever.”

ESP32 is a lot easier and the original chip has BT classic support – required for BT SPP which is what we’re using. This test uses the Arduino IDE, we are uploading code from the IDE ‘transparently’ to the COM port which the operating system makes when you pair to a BT SPP profile device. Since we pass the baud rate and control lines, we’re able to auto-reset and transmit data as if it were connected with a USB cable! here, we’re uploading a NeoPixel test sketch and it seems to be working – video.

UPDATED GUIDE: Deciphering Strange Arduino Code

This is a guide about weird code. Not necessarily bad code, but weird.

It explains a few lesser-seen elements of C syntax. “The Arduino language” is really C++, which is basically C with added flavor crystals. C was developed back in the early 1970s and has become one of the most widely-used programming languages. With such a long and diverse history, you’re bound to find some odd creatures under the floorboards.

There are a couple of reasons this might be of interest:

  • To expand one’s own C (and C++, and thus Arduino) programming knowledge; maybe there’s valuable tips here to use.
  • To write code that’s friendlier to newcomers; maybe these are things to avoid. If it confused you, it may confuse others, and that’s not ideal for teaching!

Adding an Adafruit Feather Huzzah ESP8266 or ESP32 v2 + a FeatherWing 128×64 OLED to a MightyOhm Gieger Counter to automate data collection: WhyzaGC.

I am always on the lookout for unique and interesting kits to build which led to me discovering the MightyOhm Geiger kit.

While there are a couple of other Geiger kits around, the fact that the MightyOhm was in stock ( rare in these post covid times! ), it included a commonly used detector tube ( for relative data comparisons ), its serial output, along with its steampunk looks, it had me sold.

I initially started with the ESP8266 and then ‘upgraded’ to the ESP32 to take advantage of the dual core as I ran into limitations multitasking on the ESP8266.

As such I would recommend the Feather Huzzah ESP32 v2 over the original ESP8266 version due to both the NeoPixel RGB LED and dual core functionality. That said, if you have a Feather Huzzah ESP8266 already, it will work just fine.

I also discovered Radmon.org which seemed a worthwhile project to contribute data to. It has a very simple and easy registration process…and runs on solar power!

You can check out the thorough tutorial with Arduino code on GitHub.

Collin-Wentzien made this high quality wireless scoreboard. Perfect for school games and more! Full details on Electro Maker io:

My name is Collin and I am a 16 year old maker. Today I’m going to show you how I built a scoreboard back in 2019 (when I was 13 years old); featuring a wireless controller, bright lights, and a super loud horn. I’ll also show you all the parts needed and briefly explain how I built it, in case you want to make one yourself.

MCUVoltage measures the voltage supply (Vcc) of Arduino without extra components. Supported board includes Uno, Leonardo, Mega as well as the ATtiny3224/3226/3227. This library also supports oversampling and averaging. Hardware oversampling for the ATtiny3224/3226/3227 is also supported.

While the Vcc is often assumed to be 5V for the Arduino, it is often not the case. Due to factors like having diode on the power rail, long USB cable, inaccurate bus voltage etc., Vcc can vary, usually between 4.5 to 5.25V.

Since analogRead() uses the Vcc as a reference by default, it may be useful to know the actual Vcc instead of making an assumption that it is 5V.

While the out-of-the-box measurement using this library may not be better than the 5V assumption, this library allows for calibration of the Vcc reading, and is able to achieve consistent results across various USB power supplies. Sadly, needs to be done on a board by board basis. An example, Calibrate_Bandgap is included to help with this calibration along with a digital multimeter.

This library is also useful for battery powered projects to read the current battery voltage, assuming it is hooked up directly to the Arduino.
