• Accessing an Arduino ESP32 Web Server

  Posted November 19, 2023  in Internet of Things (IoT), ESP32
  

  The third (and, I think, final) article in this series. In this post, I show the different options for connecting to the ESP32 web server highlighting the limitations and restrictions that apply to make your life miserable.

• Using UDP Broadcast to Synchronize Actions Across Arduino Devices

  Posted November 5, 2023  in Arduino, ESP32, Internet of Things (IoT)
  

  Describes a way to synchronize actions or activities across multiple Arduino devices using UDP (broadcast and receiver).

• Arduino UDP Broadcast Receiver

  Posted November 2, 2023  in Arduino, ESP32, Internet of Things (IoT), Flutter
  

  I created an Arduino sketch that implements an UDP broadcast receiver which allows me to control multiple Arduino devices simultaneously from a mobile app.

• Glowing Pumpkin Project Refresh

  Posted August 30, 2023  in Arduino, ESP32, Internet of Things (IoT)
  

  Years ago I published a several Glowing Pumpkin projects: Arduino Glowing Pumpkin and Arduino Glowing Pumpkin (Adafruit Feather). Both projects used Arduino compatible devices plus either one of the Adafruit multi-NeoPixel devices or a NeoPixel shield. The shield approach was easy because I just had to solder some male and female headers to the boards and press them together into a unit. My first project used the NeoPixel Ring which required soldering wires and running them into an enclosure where the Arduino device resides.

• Arduino ESP32 Web Server on a Processor Core

  Posted August 27, 2023  in Internet of Things (IoT), Arduino, ESP32
  

  The second article in this series, describes in detail how to run a web server in an Arduino project on the Espressif ESP32 microcontroller.

• Arduino ESP32 Running Tasks On Multiple Cores

  Posted August 25, 2023  in Arduino, ESP32, Internet of Things (IoT)
  

  This article demonstrates how to assign different tasks to separate processor cores using the Arduino platform and multiple core microcontrollers. I always wanted to learn how to do this, but the examples on the web are so full of ads that I wanted to publish a version with no advertisements as a super clean example.
