ESP8266 Community Forum

That sounds so easy, right

This is probably a redundant question, but being a noob I wanted to ask it. Could you recommend any doc/guide you followed to help you get to the point of understanding capacitive buttons' with the ESP8266? That way I'm not taking up too much of your time

I looked up the internal pull up resistor, and believe it is on "GPIO0", or D3 of NodeMCU. http://www.14core.com/wp-content/upload ... agram1.png

If I am reading your code correctly, how would modify your original sketch?
#define send_pin 12
#define float_pin 14

At the moment you are using pins 12, and 14. If I am understanding it correctly, would I modify one of the pins to point at "0" and wire the other one to GPIO14? Thus making the change:
#define send_pin 0
#define float_pin 14

Thank you so much for your help. I really appreciate it.

All GPIO on ESP have internal pullups, although they are "weak", except GPIO16 which has an pulldown instead.

Did you fin any solution? I'd like to use CapSense library in D1 mini.

thank you!
