Getting Started with NodeMCU Wi-Fi Development Board | ESP8266

NodeMCU is a popular Wi-Fi based Development board in IoT Projects. Its predecessors are ESP-01, ESP8266-12E. The NodeMCU is based on ESP866 Series.As the name suggests it is a development board, it contains additional circuitry for Power supply USB, Communications, etc (Similar to an Arduino Uno is built around ATMEGA328 IC). Hence this board has built-in voltage regulators to...

Voice Controlled Home Automation | Google Assistant | NodeMCU

In our previous tutorial, we have created a Home Automation using NodeMCU and Blynk. Using Blynk, we can control the devices anywhere in the World. We connected our NodeMCU with an optocoupler based relay and programmed it with Blynk code. Actually, it's very simple and no programming knowledge is required.Now in this tutorial, we will add an additional feature...
