I wanted to test connecting the Nano RP2040 Connect to my RPi4 MQTT server by publishing temperature and humidity data from a BME280 sensor.  I figured that this should be fairly easy since I've already used the BME280 with another RP2040 board - the SparkFun Pro Micro RP2040 and I've used my MQTT server with multiple ESP32 devices.   Of course, the devil is in the details...   I stayed within the confines of the Arduino IDE hoping that it would makes things simpler, and it did, ...
Continuing my journey with the Nano RP2040 Connect, I'll try connecting with and displaying data on the Arduino IoT Cloud.  I'll admit that I don't use the Arduino IoT Cloud much.  I prefer local data processing and storage.  I have an RPi4 dedicated as an always on Home Controller and MQTT server.  The last time I used the Arduino IoT Cloud was with a MKR1010 back in March 2019.  The User Interface is a lot more polished now, but the limits of the Free Plan are still ex ...
It seems that when it comes to machine learning on embedded devices that I discover something new almost every day.  I just got a Nano RP2040 Connect and one of the featured tutorials is "Using the IMU Machine Learning Core Features".  The Nano RP2040 Connect uses an LSM6DSOX IMU module.  I was aware that ST IMUs have the capability to generate interrupts based on events such as free-fall, single-tap, and double-tap, but I hadn't heard of the Machine Learning Core feature that is ...
For celebrating Arduino Day 20201 , here is an amazing mashup project: a Talking Useless Box called the Switch of Enlightenment.   Like all useless boxes, throwing the switch will cause a servo controlled arm to turn the switch back off after a random time delay. In my build version, an ISD1760PY voice recorder is also triggered to utter some useless, but funny, comments  or sound effects.   The ISD1760PY is unique as the voice recordings can be changed on the fly. The ISD1760 ...
For my Arduino Day 2021 Project I built a controller for my solar powered crawlspace vent fan.  I provided an overview of the project in a previous post - Arduino Day 2021 Project Intro .   The following documents my implementation.   Bill of Material:Product Name Manufacturer Quantity Arduino Nano 33 IoT Arduino 1 LM2596 Buck Converter Module 1 HW-803 5V Relay Module 1 BME280 Temperature Sensor Board 2 M5StickC Plus M5Stack 1 Raspberry Pi 4 2GB Raspberry Pi 1 SPDT Slide Sw ...
I thought I should provide a brief overview of my project that I'll submit for Arduino Day.  Tariq sent me an Arduino Nano 33 IoT to use in my project.  Thanks Tariq!  I was a bit surprised that it was shipped directly from Farnell in the UK, but I'm guessing there wasn't any US stock - probably a pandemic side effect....   A few years ago the Energy Trust of Oregon was offering incentives to install upgrades to reduce energy usage and I took the opportunity to add thermal r ...

Black girl magic

Local teenager Kamogelo Mmela (16) says she has the innovative ideas for the 4th industrial revolution and some workers and philosopher's in the AI and computer science sector totally agree, unfortunately we could not share more on what exactly is Kamogelo Mmela's "innovative ideas", but she has mentioned that she would gladly like to be part and one day have 'shares' a Vodacom, this young girl has also mastered how to do C++ and very much  confident with her coding skills, 'she says'   ...

Hi all This is a project that I've build a time ago to have some ambient light in photos I've taken of some projects that I did to display in Arduino day in my town. Using 4 potentiometers you can change the LED color and brightness .     Materials needed Arduino - I've used a Micro Pro 4x 10k potentiometer 1x Adafruit Neopixel stick - or compatible 1x 18650 battery 1x 18650 battery holder Toggle Switch ON-OFF DC-DC Mini Step Up Power Module 1-5v to 5v boost converter   ...
INTRODUCTION At the end of every year, I try to do a project with hardware/software I had not explored before.  Having a little over 10 years of exploring microcontrollers, I came across something I never bumped into when researching my prior projects.  Searching element14, I found that there are very few posts on it despite it being the father of the Arduino IDE.  So, I thought I'd share as I see it as a major tool in the tool kit.   What I found was the language ecosystem ...
This project demonstrates how to use Pmod MTDS, a capacitive touchscreen, with multi-touch support, with Arduino Mega. In this demonstration, after displaying some text messages, different shapes will be displayed. By touching the display with two fingers, the shape can be changed, and by swiping across the screen with one finger, the color of the shape can be set.   Parts list Pmod MTDS: Multi-Touch Display System Arduino Mega 2560 REV3 Required software Arduino IDE Multi-Touch Display S ...
Hello Everyone,My name is Harji Nagi.I am currently a third year student studying electronics and communication engineering from Pranveer Singh Institute Of Technology,Kanpur(UP).I have a keen interest in robotics,arduino,Artificial Intelligence and Analog electronics. The word “gimbal” is defined as a pivoted support that allows rotation of any object in a single axis. So a three-axis gimbal allows any object mounted on the gimbal to be independent of the movement of the one holding ...

Ще в далекому 1984 році я купив дуже сучасний програвач вінілових дисків, який був на той час дуже сучасним і дуже дорогим для роботи в СРСР. На той час це було круто. Але час минув, і я підкреслив момент, який забув про це, але #COVID відкрився протягом багатьох днів і слухав старі колекції. Але це диво було СРСР не включено ...
