DIY Wi-Fi Jammer using NodeMCU ESP12

There is a Wi-Fi protocol called 802.11 which act as a deauthentication frame. This is used to safely disconnect all the users connected with the router. To disconnect any device from some Wi-Fi network, it is not important to know the password or to be in the network, you just need mac address of the Wi-Fi router and client device and it is enough to be in its range of that Wi-Fi network.

Alexa Voice Controlled LED using Raspberry Pi and ESP12

In previous tutorials we have seen How we can build an Amazon Echo Speaker and then how can we control any Raspberry Pi GPIO using Alexa Voice. Now we are making an IoT project to control home appliances from anywhere in the world using AlexaPi and ESP-12E (or any ESP board).

ESP32 Internet Clock

To minimize hardware requirements we will make Internet clock without using RTC module. This is more accurate as compare to RTC clock. ESP32 is a Wi-Fi module and can be easily connected to the internet so we will use NTP (Network Time Protocol) and UDP (User Datagram Protocol) to fetch Time from the internet using Wi-Fi.
