The kids and I are building a Arduino powered marble roller. It is a “demo” project for us to learn how to use servos, steppers, input, output, lights, transistors, h-bridges, and so on and so forth.
Hot-glue and foam-board are a great prototyping material!
Ok, so if you haven’t heard about it, Arduino is a really cool piece of “open source hardware”. In simple terms, it is a single board computer with a number of analog and digital inputs and outputs, that can be programmed from your computer, but run independently.
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
I recently got this starter kit from Amazon.com:
And have since been playing with making different circuits, etc… It has been a good experience in working with lower level electronics (ohm’s law, etc…)
Hope to post more soon!
