like adding different pull up resistors ,capacitors ,logic converters but still nothing worked ...what I should add or modify with project to work with esp8266 nodemcu v3 like it worked with esp8266 d1mini ?...should I add voltage regulator as I heard there is a difference in this area...
One of our favorite Arduino-compatible boards is the NodeMCU, pictured below. We love it so much thatwe called it the Arduino-killer. It's tiny, has Wi-Fi built-in, and can be bought for as little as $3. It's perfect for compact internet-of-things and home automation projects. Mean...

I purchased a NodeMCU ESP32-S to bring in some 0-10v analog inputs. I've converted them down to 0-3.3v but I've found the same issues as in this thread. Below about 0.2v there is nothing, above 3.1v same thing. Between 2.9 - 3.1 I get a lot of noise and bouncing even ...
I moved on to ESP8266 NodeMCU boards fairly quickly. I might have moved on to ESP32, but by then I was out of things to do that might have benefited from it. ESP8266 is everywhere now. A vast number of commercial IoT devices for WiFi-based "smart home" ecosystems use them. Reply...
AFAIK power should be good. It comes from the FTDI (probably fake) USB-TTL adaptor and is 3.5v. On the reset pin I have a100n cap to gnd, a 10k pullup to vcc and a 330 connection to gpio16. Reset seems to always work. in the sense that the boot (after deep sleep) always sta...
- RPI is supported by my toolchains for espressif micro controllers (esp-idf, nodemcu, arduino). (I still run on 32 bit because stability is more important than performance). So my project really started when I could check all those requiremen...
(literally) will take various readings, and send them to a centralized server. The nodes will be using either 12E or 12F versions of ESP8266 modules so I can more accurately control their power usage with Deep Sleep and better regulators than come on the WeMos, NodeMCU versions. Looking to...
...the auther of the project code his design uses espminid1 and he told me I can use the main code on esp8266 nodemcu v3 as that is the one I bought as I found it only in the store (my design uses nodemcu v3 ) ...so what are the hardware differences or issues that cause tha...
