The tutorials, code, schematics, wiring diagrams and other material on MicroControllersTech are shared to help you learn and build. Please read this page before you use them.
Provided as-is
Everything on this site is provided “as is”, without warranty of any kind, express or implied. That includes any warranty that it is accurate, complete, fit for a particular purpose, or free of errors. I test every project on my own hardware, but your boards, parts, tools and software versions may differ from mine, and manufacturers change their products and documents over time.
Use at your own risk
Electronics work carries real risks: damaged boards and components, lost data, overheating batteries, and electric shock from mains-powered equipment. You are responsible for checking that a design is safe and suitable for your use, for following the manufacturers’ datasheets and safety instructions, and for working safely. Never work on mains voltage unless you are qualified to do so.
The projects are for learning and prototyping. They are not designed or certified for safety-critical, medical, automotive or life-support use.
Limitation of liability
To the extent the law allows, MicroControllersTech and its author are not liable for any loss or damage, direct or indirect, that results from using or relying on anything on this site, including damage to hardware, loss of data, or injury.
Code and downloads
Source code published with the tutorials is covered by the license included with each project (usually the MIT License), which carries its own no-warranty terms. Code that comes from a manufacturer, such as STMicroelectronics HAL drivers or vendor libraries, remains under that manufacturer’s license.
Third-party products, documents and trademarks
Datasheets and manuals offered for download in a tutorial are copies of the manufacturers’ own documents, kept here so the links keep working. They remain the property of their owners, and the manufacturer’s current version is the authoritative one. Product names, logos and trademarks belong to their respective owners, and mentioning them does not imply endorsement.
Supplied hardware, product links and donations
When a manufacturer has supplied hardware for a tutorial, the post says so at the top. That does not affect what I write: the tutorials describe what I found on the bench, including the problems.
Links to parts on Amazon and other stores are there for convenience, so you can find the exact parts I used. I don’t earn anything from them. The site is supported only by reader donations, which are voluntary and don’t change what you get.
Found a mistake?
If something in a tutorial is wrong or out of date, please let me know through the feedback survey at the bottom of the post or on the forums, and I will try to correct it as soon as possible.
