A major part of any new IoT project involves integration and interfacing nowadays. In IoT world we have a lot of proprietary technologies and thus a good number of protocols and interfacing techniques like UART, SPI, I2C, PCIe, SWP, DWP, which makes the life of a new IoT Engineer really challenging. In 3 in 1IoT Bundle, we consider all those scenario in details and step by step manner.3 in 1 IoT Bundles cover the integration of each popular hardware with its SDK hands-on. Most of this IoT development platform has its own pros and cons which is covered in details with use cases 3 in 1 IoT has covered majorly hardware side of IoT, as this is the first and major point where software developers face challenges. We have covered 4 major hardware development and integration, which is Arduino Uno, Raspberry Pi, Konnect KiT, and wireless-enabled ESP8266. Why you should consider taking this course? One of the challenges while working with ESP8266 is its learning curve. Tools and techniques which one needs to master to get comfortable while using it in projects need to be understood well with a clear understanding of basics. Keeping that in mind we have designed the Professional ESP8266 development course. This course will cover all the concepts one needs to master starting from basics, you will learn how the Architecture of ESP8266 is designed, then you will understand how the flashing is done in ESP8266 where you load your OS, connecting ESP8266 to the internet is then the major step where you will understand the capability of hardware to communicate with the internet which will enable the IoT. Most of the time hardware endpoints will be connected to the data stream network cloud which can manage scale, security, and a stream of communication. We are using a widely used platform which is PubNub with ESP8266 to demonstrate this. In the end, we will put everything together and also have a small end to end project of a smart home where we will cover circuit design, development, and implementation with Go-Live.
