Starting out with DIY Projects

 



This article is only a companion piece to the YouTube video My Hands Are Sweating! Building Your First DIY Electronics Projects. Many folks are intimidated or believe that a workshop full of advanced electronics gear and specialty tools are required to build your own smart devices or other small electronic projects.  
The video shows that you can start building a number of various sensors and devices with absolutely no tools and just a few low cost components.  From there, slowly adding a few basic tools as your experience increases allows you to build a bit more complex devices.  This article primarily follows along with that video and just lists the parts and a couple of the wiring diagrams shown as reference material.

So please watch the video as this article will only provide links to the parts shown and references like a few wiring diagrams for the video.
