Which is better Arduino Uno or NodeMCU?
In common the NODEMCU is based on the ESP8266 microprocessor have a very low current consumption between 15 µA and 400 mA which can be further decreased with the deep sleep mode activated to 0.5 µA. The current consumption is then a factor 70000 higher in deep sleep mode for the Arduino Uno with 35 mA.
Is NodeMCU ESP8266 Arduino?
Search the word ESP8266 in Boards>boards manager from Tools menu. After complete installation, you will see the INSTALLED label on ESP8266 boards. After these two steps, you can see ESP8266 based boards such as NodeMCU in your Arduino IDE boards list, and you can choose your desired board to upload the code.
What are the limitations of Arduino UNO?
Disadvantages:
- It’s mostly still AVR (8-bit) “eco-system” (and +5 V).
- If you need more processing power and working memory be ready to kiss goodbye Arduino environment pretty soon.
How to wire the ESP8266 module on Arduino?
In this illustration we will going to wire the ESP8266 Module on Arduino but before we can proceed we need to setup the ESP8266 module using AT-COMMAND please refer to this link. As you can see the illustration below our host control is the Arduino MCU board that controls the ESP8266 and the 4 channel relay.
How to use Arduino WEMOS D1 WiFi Uno ESP8266?
Insert the Auth Token, Network name, and Password to your programming. Now upload the code to your WeMos D1 (ESP8266) through micro USB. Make sure you use the right port by select at [Tools => Port]. Select the play button from the upper right side and turn on the pin button. Now it’s working!
Which is the host control for the ESP8266?
As you can see the illustration below our host control is the Arduino MCU board that controls the ESP8266 and the 4 channel relay. By removing the ATMEGA328P Chip we consider that were going to use the TTL UART of the Arduino.
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.
