Arduino PLC
https://www.youtube.com/watch?v=mq1xgubaQeA
The Arduino PLC and the Arduino PLC IDE… there has been a lot of buzz around it since it was announced recently. I’m a long-time user of the Arduino eco-system and have been using their IDE for over 10 years for various projects. Guess if I was surprised when they released their new IDE aimed at the industrial automation industry! The Arduino PLC IDE only supports one board right now, the Arduino Portenta Machine Control, and luckily I had just been using one of these boards for another project recently, so I could try the new PLC IDE that Arduino have released.

This DIY Apple Pencil writes with gestures
https://blog.arduino.cc/2023/01/20/this-diy-apple-pencil-writes-with-gestures/
Released in 2015, the Apple Pencil is a technology-packed stylus that allows users to write on iPad screens with variations in pressure and angle — all while communicating with very low latencies. Nekhil Ravi and Shebin Jose Jacob of Coders Café were inspired by this piece of handheld tech to come up with their own pencil concept, except this one wouldn’t need a screen in order to function.

Better Macro Images With Arduino Focus Stacking
https://hackaday.com/2023/01/26/better-macro-images-with-arduino-focus-stacking/
If you’ve ever played around with macro photography, you’ve likely noticed that the higher the lens magnification, the less the depth of field. One way around this issue is to take several slices at different focus points, and then stitch the photos together digitally. As [Curious Scientist] demonstrates, this is a relatively simple motion control project and well within the reach of a garden-variety Arduino.

“Built on the Mega’s familiar form factor, the GIGA dwarfs the power of its cousin with a dual-core Cortex-M7 + Cortex-M4 microcontroller, which allows two Arduino sketches to run concurrently on a single board – or one traditional sketch, plus a MicroPython script.”
It’s only fitting to see the most powerful Arduino board for makers on Make: Magazine!
Mega Arduino announcement has GIGA impact
https://makezine.com/article/technology/arduino/mega-arduino-announcement-has-giga-impact
As useful as the venerable Uno can be for many projects, when makers need more IO, more power, more…everything, they typically find themselves reaching for the beefier, connector-laden Arduino Mega. At least they might have…until the announcement of the new GIGI RE Wi-Fi, the most powerful Arduino board for makers.
Built on the Mega’s familiar form factor, the GIGA dwarfs the power of its cousin with a dual-core Cortex®-M7 + Cortex®-M4 microcontroller, which allows two Arduino sketches to run concurrently on a single board – or one traditional sketch, plus a MicroPython script.
Despite the common layout, the GIGA increases the Mega’s pin count to a mind-blowing 76, including 12 analog, 13 PWM, 4 serial ports, 3 I2C, 2 SPI, 1 FDCAN, and 1 SAI. This, plus USB-C, USB-A (host), and a 3.5mm audio jack makes the GIGA a veritable playground for music projects, HID (human interface device), machine learning/vision, robotics, and more.

Kehittäjien suosima Arduino-kortti on saanut valikoimaansa toivotun lisäyksen, kun Mega-koon kortilla on tuotu kaksiytiminen prosessori. Tämän ansiosta samalla kortilla voidaan ajaa kahta Arduino-ohjelmaa samanaikaisesti tai Arduino- ja MicropyThon-koodia rinnan.
Uusi kortti on nimeltään GIGA R1 WiFi, ja sen Cortex-M7-ytin operoi 480 megahertsin kellotaajuudella ja M4-ydin 240 megahertsin kellolla. WiFi-tuki tulee ensimmäistä kertaa Mega-formaattiin Arduinossa.

Sometimes the only motivation you need for a project is “because I want to.” That is especially true for cute and quirky decoration that doesn’t need to prioritize functionality. The perfect example of this is Ruby Zoom’s Lamptopus, which is the most adorable desk lamp in the world.
