Arduino is a powerful tool and brings a new way of discovering and thinking that how we can make use of Electronic technology in real world by making smart things. Arduino is providing a new, guided and practical approach to students, hobbyists and professionals to use electronics and sensors to next level and create live projects that make the life smart and take the current electronic technology to next level. Handbook of Arduino is highly technical and practical oriented book to teach anyone how to handle Arduino, make simple things work, interact with Sensors and above all make Live Real Time Electronic Projects. All the users need is an open mind or a problem to fix and you will find tons of ways to take Arduino as the center point to fix the problem creatively.
