In our case, we use NODEMCU ESP8266, but you can use any other type of ESP8266 with all pins exposed. In our program, we connect D0, D1, D2, and D3 in a circuit, which controls the relays. The relays are using 5V. ESP8266 is using 3.3V. To connect the 3.3V ESP8266 to the 5V relay module, we use one NPN transistor 2N2222.

First Steps with the NodeMCU ESP8266 Wi-Fi Module. In our previous tutorials we were using already the NodeMCU ESP8266 Wi-Fi Module and we discussed about "Security", "Cyber-Security" issues while using "IoT", "Internet of Things" and the importance that the router MUST be protected by a NEW password and NOT ALLOW to let connect any…

What will you make:

In this article, we will learn how to monitor temperature and humidity with your smartphone device, using a platform called Blynk. Blynk allows you to control Arduino, ESP8266, Raspberry Pi and other such boards through their iOS and Android apps. It provides an easy to use dashboard through which you can monitor various sensors and control actuators. If you are completely new to Blynk, checkout our Getting Started with Blynk guide.
