We also want to use that push button as a manual override for turning the relay on and off in addition to being able to control the relay via the WiFi link. You can prevent this by inserting a 470 ohm (or similar lowish value) series resistor to limit the current from the RTS pin. The button input looks identical to the submit, but they are not interchangeable — the button input does not submit the form. The sketch also checks the button push counter's value, and if it's an even multiple of four, it turns the LED on pin 13 ON. MicroPython is an open source implementation of Python 3 that includes a small subset of Python standard libraries and is optimized for execution on microcontrollers with limited ROM and RAM. Depending on the states of the columns, the microcontroller can tell which button is pressed. About NodeMCU. But on some occasions, you may want to build your own external reset button.
