Secure boot : Secure boot is a security standard developed by members of the PC industry to help make sure that a device boots using only software that is trusted by the Original Equipment Manufacturer (OEM). When the PC starts, the firmware checks the signature of each piece of boot software, including UEFI firmware drivers (also known as Option ROMs), EFI applications, and the operating system. If the signatures are valid, the PC boots, and the firmware gives control to the operating system. -Microsoft If you are bored of reading here's a quick video for you: Though secure boot prevents your computer from executing code that is not suppose to run on the machine, it creates problem for pc enthusiast who likes to play around with different OS. We can turn off this feature from the BIOS and continue exploring the universe of OS without any issue.

There has been a lot of development in the field of ioT and smart homes. We live in a era where most of our devices are connected to the internet. Raspberry Pi was launched in 2012 and with it there was a rise in several IoT Smart home applications. But the problem was that raspberry pi was a bit costly. Here in India it was available for around 3000 to 4000 rupees. We had Arduino uno before but it lacked Wi-Fi and adding external wifi module was a headache. But in 2015 a new device surfaced in the market with built in wifi. It was the node mcu. It was not as powerful as raspberry pi and it didn’t even run linux os but it was powerful enough to compute and control other devices. It was the perfect cheap alternative to develop iot projects. Later ESP32 was developed with more features and processing power. That’s enough history now let me explain how I managed to develop a smart home project. The goal : We should be able to control the lights using wifi. The Idea : ESP32 / Node...
