Part of my project with the Arduino Portenta requires some lighting and I wanted to be able to individually control them. I asked a model railroad mate and he suggested NeoPixels. They only require 3 wires, run on 5v and can be controlled from a range of microcontrollers. The standard ones do RGB values but there is also a variant with an additional white LED. I found some on a small breakout that did RGBW and could be bought in packs of 10.   After experimenting with a couple of differe ...
Since December 2020, I've been dabbling in satellite communications. I've successfully captured SSTV images, FM and APRS data from the International Space Station. Most of this was accomplished using a handheld transceiver and portable Yagi antenna. This is a Slow Scan TV image (SSTV) I captured. Then I discovered the SatNOGS project. https://satnogs.org/ "A global network of satellite ground stations, designed as an open source participatory project." https://wiki.satnogs.org/Main_Pa ...
From my previous experiments with the Portenta H7, I had installed a multi-core version of blink with one core flashing green and the other blue. I was keen to know if the M4 core would still boot if I loaded MicroPython code on the M7 core.   I clipped on the Vision shield and plugged it in. Arduino recommend using the OpenMV IDE for developing for this shield, so I fired that up and pressed the connect button. It failed to find the board so I gave the reset button a double-tap and presse ...
I decided to take a look at the Portenta H7 to experiment with its vision and multicore capabilities.   What's in the box? There's not a lot in the box, just the Portenta board, a warranty note and tucked underneath an antenna that plugs into the UFL Connector for the Wifi and Bluetooth. However, that does not mean you are not getting a good deal, the Portenta board is crammed with features:   There is a dual-core microcontroller (STM32H747) with built-in graphics capability, Wifi ...

New Arduino Docs Site

Posted by ralphjy Top Member May 29, 2021
I just got my Nano RP2040 Connect and discovered that the Arduino team has recently completely revamped their online documentation as described in this blog post on May 17: https://blog.arduino.cc/2021/05/17/arduino-docs-has-all-the-info-you-ever-need-about-arduino-boards/ .   And here is the link to the new docs homepage: https://docs.arduino.cc/   The boards are organized by families: MKR Classic Nano   The Portenta has been split off into a separate Arduino Pro Documentat ...
I noticed that the Arduino Nano RP2040 Connect  is now available in the Arduino store.  I've been waiting for this board as it adds WiFi and BLE capability to the RP2040  and also adds a microphone, IMU, and 16MB of flash memory.  I can't wait to try it out.  I've seen some complaining about the high cost - $25.50 and the lack of a USB-C connector, but I remember when the Uno was about $20 and we've come a long way since then.  It is already supported in the Arduino ...
For Arduino Day, belated, a few photos of a project I'm working on. Arduino MKR 1310 LoRa with Ethernet shield and CAN-shield. In a DIN mounted housing and a LoRa range antenna. It is going to be part of a light industrial test setup.   The housing is Arduino MKR DIN rail housing from e14 member hwhardsoft. Inside: Arduino MKR 1310 for LoRa, with a MOLEX 105262 868/915 flex antenna. Arduino MKR ETH shield Arduino MKR CAN shield     This will be one of a few replaceable ...

Running Machine Vision on the Arduino Portenta + Vision Shield   What you see in this video is the Arduino Portenta running a Machine Vision algorithm to classify empty spaces and Lion / Jaguar figures. I wrote two detailed posts to explain how to achieve this in a fast and accurate way, see the links bellow and pay special attention to the second one because the training / correction / retraining process is what will allow you to achieve these levels of accuracy.   The portenta offers ...
The basic idea was to create simple air quality monitor. I have used the PMS7003 sensor which is able to measure PM1.0, PM2.5 and PM10.0. This sensor was connected to the Arduino Nano Every. Received data from sensor is available via serial port in human readable format. Additionally, an alert appears when PM2.5 and PM10 exceed the safe limit (the built in LED is this indicator). Below there is diagram with connections: In the final solution will be nice to add three RGB leds which by color c ...

Hi Guys,   I am kinda new in here. I got this project where we need to detect spilled or leaked water under a drilling rig so before it gets overflow, the sensor would detect it and an alarm system goes off. The only problems is the water is mixed with mud, oil or grease and all the other stuff you could think of while drilling in outbacks of Australia. So this project related to environmental protection. Any suggestion would be highly appreciated.   Kind Regards Manni ...
