How do I reset my Nodemcu?
Manual reset and manual program
- press and hold the reset button.
- press and hold the program button.
- release the reset button, the ESP will boot in program mode.
- release the program button.
- upload the sketch.
How do I connect my Arduino Nano to Nodemcu?
Set both switches on the power module to 3.3V.
- Insert an Arduino Nano on the other end of the breadboard:
- Connect wires to the ESP8266 (only to the pins we will actually use, the the schematic below):
- Now connect everything according to the scheme:
- Now connect a second USB cable to the Arduino Nano.
All you have to do is press the momentary push button mounted to the top of the board, and your Arduino will reset.
How do I remove a code from NodeMCU?
In case you wish to remove a python script from the board then you’d have to use “ampy”. So lets say you have a file by the name “blink.py” on your nodemcu then you’d have to do- ampy -p /dev/ttyUSB0 rm blink.py.
The reset button does pretty much the same as unplugging the board and plugging it back in. It restarts your program from the beginning. The same thing happens when you program the board – the USB interface presses the reset button for you.
How to connect Arduino Nano to NodeMCU via USB?
Nano has one Serial, which is connected over USB to computer too. So there too you can’t use the USB and RX TX pins at the same time. You could use SoftwareSerial to connect to NodeMCU. The Nano TX to esp8266 RX should have logic level conversion to not to send 5V to esp8266 3.3V pin.

Can a nano send 5V to an ESP8266 RX?
The Nano TX to esp8266 RX should have logic level conversion to not to send 5V to esp8266 3.3V pin. Thanks for contributing an answer to Arduino Stack Exchange!
