100+ DIY IoT Projects with Code and Schematics

Internet of Things (IoT) is revolutionizing the electronics industry. With more and more applications adapting IoT, it is important for the engineers of today to get acquainted with this technology. To help you with the same, Circuit Digest provides you with a large collection of free IoT projects for you to learn and recreate. The projects are built using the popular development platforms like Arduino, Raspberry Pi, ESP8266, STM32, MSP430, PIC amongst others. All projects are documented with a neat circuit diagram, code and demonstration video to provide a complete do-it-yourself experience.
