Interface I2C LCD Using NodeMCU : 4 Steps (with Pictures ...

https://www.instructables.com/id/Interface-LCD-Using-NodeMCU/

Connecting LCD to I2C and then interfacing it to NodeMCU is very simple. The LCD’s registers from D0 to D7 and Vcc, GND, RS, R/W pins will be connected to I2C.. GND pin of I2C is connected Ground pin (GND) of the NodeMCU.. VCC pin of I2C is connected Vin pin of the NodeMCU. (Because we need to supply 5v to LCD) SDA pin of I2C is connected D4 of the NodeMCU.. SCL pin of I2C is connected D3 ...

Interface DHT11 (Humidity Sensor) Using NodeMCU : 6 Steps ...

https://www.instructables.com/id/Interface-DHT11-Humidity-Sensor-Using-NodeMCU/

Wiring the DHT11 to the NodeMCU is really easy, but the connections are different depending on which type you have either 3-pins or 4-pins.. The wiring connections are made as follows : Pin 1 of the DHT11 goes into +3v of the NodeMCU.. Pin 2 of the DHT11 goes into Digital Pin D4 of the NodeMCU.. Pin 3 of the DHT11 goes into Ground Pin (GND) of the NodeMCU.

ESP8266: NodeMCU Pin mappings – techtutorialsx

https://techtutorialsx.com/2017/04/02/esp8266-nodemcu-pin-mappings/

Apr 02, 2017 · So, for example, pin D1 of the board doesn’t map to GPIO1 of the ESP8266 (it actually maps to GPIO5). Naturally, if this is not taken in consideration, it will lead to a difficult debugging process, since we will be assuming that the board is not working correctly. So, the correct pin mapping is the following [1][2] (NodeMCU on the left and ...

NodeMCU ESP8266: Details and Pinout : 11 Steps - Instructables

NodeMCU ESP8266: Details and Pinout: Today, we will talk about ESP8266 pinning, or in other words, NodeMCU. Personally, I really like this component, as it already comes with USB input. But it is important to explain that the NodeMCU is formed by an ESP12E, which still has an ESP8266...

ESP8266 NodeMCU not detected by computer. · Issue #3551 ...

https://github.com/esp8266/Arduino/issues/3551

I bought some spinoff ESP8266 NodeMCU, which is not really the NodeMCU, but a piece of hardware called "HW-628 V1.1". I installed ALL THE DRIVERS on the internet (really, like at least 15 different) and then I read somewhere about those spinoffs not coming with any software installed on them, and thats apparentely an issue.

NodeMCU GPIO with Arduino IDE NodeMCU

https://www.electronicwings.com/nodemcu/nodemcu-gpio-with-arduino-ide

We can see RX, TX, SD2, SD3 pins are not mostly used as GPIOs since they are used for other internal process. But we can try with SD3 (D12) pin which mostly like to respond for GPIO/PWM/interrupt like functions. Note that D0/GPIO16 pin can be only used as GPIO read/write, no special functions are supported on it. Example

NodeMCU - Vin pin as 5V output? - Arduino Stack Exchange

https://arduino.stackexchange.com/questions/51873/nodemcu-vin-pin-as-5v-output

The VIN pin not directly connected to the USB's 5V supply (at least on the LoLin v3 board). this means the pin cannot be used as a 5V supply output. You cannot control that voltage. It is always on, and always 5V (or whatever your USB port happens to provide - 4.75v - 5.25v). You must never ever connect VIN to a power source and connect the USB ...
