The 8x10" iFixit Magnetic Project Mat catches and securely holds screws as you pull them out of a device. Now you can stop worrying about keeping track of all the loose screws and focus on your repair. Screws and small parts will remain right where you left them. For laptops with hundreds of screws, use the whole mat as a screw guide and keep careful location notes. Included is a pen – made by Staedtler, producer of top-of-the-line pens and pencils for artists and architects – that was specially designed for the Project Mat. The Lumocolor Correctable pen resists smears and won't wipe away with a casual brush of your hand. When your repair is complete, use the eraser tip or a dry cloth to wipe the ink away clean. Features Organize all your small parts while you work on a device. The dry-erase surface lets you keep notes and location sketches. Reduces reassembly time by up to 40% while preventing errors.

This book covers a series of exciting and fun projects for the Arduino, such as a silent alarm, people sensor, light sensor, motor control, internet and wireless control (using a radio link). Contrary to many free projects on the internet all projects in this book have been extensively tested and are guaranteed to work! You can use it as a projects book and build more than 45 projects for your own use. The clear explanations, schematics, and pictures of each project make this a fun activity. The pictures are taken of a working project, so you know for sure that they are correct. You can combine the projects in this book to make your own projects. To facilitate this, clear explanations are provided on how the project works and why it has been designed the way it has That way you will learn a lot about the project and the parts used, knowledge that you can use in your own projects. Apart from that, the book can be used as a reference guide. Using the index, you can easily locate projects that serve as examples for the C++ commands and Arduino functionality. Even after you’ve built all the projects in this book, it will still be a valuable reference guide to keep next to your PC.

Build your textbook weather station or conduct environmental research together with the whole world. With many practical projects for Arduino, Raspberry Pi, NodeMCU, ESP32, and other development boards. Weather stations have enjoyed great popularity for decades. Every current and even every long discontinued electronics magazine has regularly featured articles on building your own weather station. Over the years, they have become increasingly sophisticated and can now be fully integrated into an automated home — although this often requires loyalty to an (expensive) brand manufacturer across all components. With your own weather and environmental data, you can keep up and measure things that no commercial station can. It’s also fun: expand your knowledge of electronics, current microcontroller development boards and programming languages in a fun and meaningful way. For less than 10 euros you can get started and record your first environmental data — with time and growing interest, you will continue to expand your system.
