100-ohm resistor Breadboard Jumper cables Circuit Diagram to Interface a Seven-Segment Display with NodeMCU Since this is a beginner-level project, the circuit is very simple as you can see in the ...

After connecting the nodemcu and relay,in my case i used two channel relay just for this prototpe,you can use whatever relay according to your switch board requirements,either 4 channel realy, or 12 ...

The battery is connected to the Vin and ground pins of Nodemcu and we can also connect the motor driver supply to this battery. Making the Circuit of the Self Watering Smart Pot I started the circuit ...

Take special note of the wiring diagram as the relay I used requires 5v and the NodeMCU is only 3.3v so and additional 5v power source is required. Also make sure your relay has the JD-VCC pin as many ...

As usual I’ll be using a NodeMCU board (I really did order a lot of them) which uses an ESP8266, but there’s no reason this would be difficult to achieve on an Arduino-based device.

NodeMCU is a LUA based interactive firmware for Expressif ESP8622 Wi-Fi SoC, as well as an open source hardware board that contrary to the $3 ESP8266 Wi-Fi modules includes a CP2102 TTL to USB chip ...

This paper presents the implementation of a distributed consensus algorithm for wireless sensor network (WSN) on a hardware platform of NodeMCU ESP8266. This study uses the minimum consensus algorithm ...
