Electrical and other Safety:

Technology and the laws and limitations imposed by manufacturers and content owners are constantly changing. Thus, some of the projects described may not work, may be inconsistent with current laws or user agreements, or may damage or adversely affect some equipment.

Your safety is your own responsibility, including proper use of equipment and safety gear, and determining whether you have adequate skill and experience. Power tools, electricity, and other resources used for some of these projects are dangerous, unless used properly and with adequate precautions, including safety gear. If you are a younger person or are inexperienced with electrical devices, ask for help from a parent, teacher or other knowledgeable person.

Princeton University has an excellent page on Electric Safety here: http://web.princeton.edu/sites/ehs/hazardcommguide/8.htm You should view and understand that page before attempting any project or use of power control devices that use or control voltages above 40 Volts AC or DC.


You must accept that You and You Alone are Responsible for your safety and safety of others in any endeavor in which you engage. While the material on http://Arduino-Info.Info and http://YourDuino.com is provided in hopes that it will enable some Arduino enthusiasts and inventors to keep experimenting and inventing, You are Responsible for verifying its accuracy and applicability to your project. You are Responsible for knowing your limitations of knowledge and experience. If you do any work with "mains power" such as 120 or 240 VAC power wiring, you should consult a Licensed Electrician.

Some illustrative photos do not depict safety precautions or equipment, in order to show the project steps more clearly. These projects are not intended for use by children. Use of these instructions, kits, projects and suggestions is at your own risk. YourDuino.com and F. Terence King disclaim all responsibility for any resulting damage, injury, or expense. It is your responsibility to make sure that your activities comply with applicable laws.
