What is NodeMCU in IoT?

The NodeMCU (Node MicroController Unit) is an open source software and hardware development environment that is built around a very inexpensive System-on-a-Chip (SoC) called the ESP8266.

How to connect NodeMCU to nrf24l01-arduino code?

I need to connect NodeMCU and NRF24L01. where I’m receiving data from another NRF24L01 Transmission. I managed to connect to a WiFi network but the data receiving is not taking place as expected. Here is my code

Where can I upload data from the nRF24L01 node?

We will upload the received data on Thingspeak Server. The NRF24L01 can receive data up to 100m distance whereas we can monitor data worldwide using NodeMCU. The sensor Node comprises of NRF24L01 interfaced with any Microcontroller Board like Arduino or NodeMCU ESP8266.

How is the NodeMCU connected to the transmitter?

In the Transmitter side, the NodeMCU is module is connected to a NRF24L01 module which acts as the Transmitter. As shown in the figure the SPI Pins of the NodeMCU are connected to the SPI pins of the NRF24L01 module.

How are Arduino Uno and NodeMCU connected?

As shown in the figure above, we have connected NRF24L01 to Arduino Uno, here the SPI Pins of the NRF24L01 module are connected to the Arduino UNO board. The data pins and control pins of the LCD are also connected to digital pins of Arduino board. A potentiometer is connected to the LCD to change the contrast of LCD display.
