The Arduino Rangefinder Kit brings together the basic components of learning Arduino into a menu based Rangefinder.

Breadboard Arduino
Placing an Atmel328PU on a Breadboard and wiring it up is an amazing start to the world beyond Arduino prototyping. Once we begin to understand that at the heart of Arduino is a chip ( Atmel328PU ) that is meant to live inside some kind of device the world of IoT begins to open.

The first pieces of how to use Docker Compose
What is Docker Compose
For me, docker-compose is a case study in the right tool for the right job. At the least, it allows us to carefully manage and maintain the instancing of our containers. docker-compose takes the command-line options for docker and places them into configuration files.

From a basic understanding of Docker, it becomes clear that it is extremely useful to house your WordPress installation inside a Docker container. Once completed your WordPress instance becomes highly portable and scalable. Additionally, there are other hidden benefits.

Potential and Kinetic Energy
This concept design for potential and kinetic energy was a first take at a larger scale participatory lesson. The students strapped a Android based phone to a skate wheel car and took measurements as the car oscillated up a down each side.
The first attempt at this ramp was not terribly successful. I will need to add rails on the side to keep cars from veering off the ramp. Also, the ramp was not quite sturdy enough for a Skateboard.
Docker Basics – Install, First Run and Basic Commands
Installing on Debian based Systems
Docker is incredibly simple to install and get started. We will be installing the repository version on Linux Mint. This installation should work on any Debian system.

Publishing to all the available Social media sites can end up being monumental. Using IFTTT, rings hollow to followers and friends. Orchestrating content from WordPress using NodeRED Automation may be my answer. Stay Tuned.
My first efforts with Node-RED and Twitter were simple and promising. I was able to send a Tweet in a matter of moments. However, as I used the “contributed” Twitter nodes I quickly realized I would need to do much of this the hard way. At this point I will be digesting the following documentation from Twitter.
- https://developer.twitter.com/en/docs/basics/authentication/overview
- https://developer.twitter.com/en/docs/basics/authentication/oauth-1-0a
- https://developer.twitter.com/en/docs/basics/authentication/oauth-1-0a/creating-a-signature
- https://developer.twitter.com/en/docs/basics/authentication/oauth-1-0a/authorizing-a-request
There is quite a bit in this documentation so I am learning both Node-RED and Twitter Authorization at the same time. If I can climb this mountain I expect I will learn many things.
