About this Event

A WiFi equipped solar powered weather station article will provide the structure for learning about the ThingSpeak IoT platform, Arduino infrastructure, a few programming statements and how to run microcontrollers on a battery with or without a solar panel.

This class is ideal for the absolute electronics/programming beginner as well as intermediate hobbyists. This is not a programming class but a few commands will be discussed to allow simple customization. We will start with an introduction to microcontrollers and sensors before moving on to creating your own free "channel" at All parts are furnished except your laptop computer.

The Wemos/Lolin D1 Mini is an exciting entry into the hobby Internet of Things market and contains a microcontroller compatible with the Arduino IDE. It is five times as fast as the Arduino Uno, one hundred times as much flash and includes WiFi. You will Make a Wemos and sensor circuit on a breadboad using a supplied parts kit, configure ThingSpeak pages, modify and download a program to the Wemos and see a slightly limited version of the authors site but using your sensor data.

You will leave class with knowledge, documentation, program and parts list to acquire parts, build your own project to monitor your world. Even if you are not interested in building a weather station, the techniques used here are applicable to many other low power applications.

BACKGROUND: Dallas Amateur Radio Club holds occasional five hour sessions where they order parts for a project, someone gives a lecture and they pull out soldering irons and other tools to each assemble a project. I recently led two of these sessions. It was a lot of fun with a lot of detail but many people would not care to spend ten hours in cllasses. I extracted the heart of the sessions to formulate a two hour DMS class. Temperature and pressure information will be uploaded. We will not be using the solar panel, power controller and battery. The PCB referenced in the article can be ordered for $5.00 plus shipping and includes a few ports which makes it very adaptable to many other type of projects.

Special Considerations and Warnings

Bring a notebook/laptop computer with a USB port. Some of the new thin notebooks do not have a builtin USB port and require a dongle.

Some MacOS computers tend to have problems running the Arduino IDE. I can give some guidance but I not familiar with using Macs. Most of them work out fine.
