esp8266

Hi everyone, I designed a PCB based on the ESP8266EX dotn here is the schematic: To flash the board I use the module: https://joy-it.net/de/products/SBC-ESP8266-PROG I am able to flash the board with Arduino IDE with a simple code: void setup() { // put your setup code here, to run once...

I am using my ESP8266 device and have installed Micropython as firmware on it. I wrote some python code to fetch environmental data through a DHT11. The scripts I'm running with the ampy module, specifically, the command "ampy --port COM5 put file.py" and the command "ampy --port COM5 run...

I am in the process of creating a reed switch module for door opening detection, and I am encountering a challenge. The reed switch available to me is a normally open switch, meaning that when the door is closed, the switch will be closed due to the presence of a magnet. As a result, the ESP...

I have recently simulated the circuit demonstrated in the provided video using Multisim. While the circuit appeared to function correctly in the video, the simulation results indicate that it is not working as intended. The output remains high irrespective of the switch state. The left switch is...

UPDATE: the sticking problem has gone away but I don't know why. I am using the Vin, which is a 4.6ish volt source, to power the pump. When the board is sensing but not pumping I measure a total draw of 30 mA using a USB J7-c digital tester. When the pump is activated but dry and not pumping...

I using the ESP-WROOM-02 (esp8266 core) as WIFI module and the samd21g18 as main processing unit. To test, I´m using the ESP-WROOM-02 DEV board kitc and an Arduino nano IOT which has also a samd21g18 MCU. I flashed the ESP-WROOM-02 via the ESP flash download tool with the [AT Firmware...

hi everyone, I'm interested to know what software or hardware you can build such graphs for consumption, bootloading or starting the firmware, performing any operations, and power consumption for esp8266, I have seen several diagrams like this on the internet. and they are designed all...

In relation to my project as documented in the Wireless&RF section , I need to solve how to count a high speed set of pulses using an ESP8266 running on esp-open-rtos. The article here already confirms that this is a true challenge and I am actually looking for another approach. I hope that the...

Hi, I have designed ESP12F with CH340G(USB- UART converter) with auto programming feature. As shown below. I have programmed in Arduino IDE. As long as power is there, the board runs the code. But After I cycle the power, the board doesn't run the program! until I hard reset the ESP12F...

Hey guys, it's my first post here, so I'm sorry if I'm doing it in the wrong place and I really hope you can help me! I'm developing a dimmer with ESP8266 and I'm having trouble with the TRIAC circuit. I have a zero cross detector developed and it works fine, but when I try to send the signal...

Greetings enthusiasts! I've joyfully immersed myself in a DIY project controlling Hue lights with a wall switch. Hoping for some tips to get me through as I haven't done any electronics since high school. In my 40s now. My main inspirations is a project on diyhue and one on this forum using a...

Hello all, First of all I'm a complete newbie about circuits and electronics. I recently bought a 3D printer and I saw this project on thingiverse. Quick sum up : LEDs (WS2812) lamp controlled by an ESP8266. The main issue is that the firmware of the ESP8266 provided to control the LEDs do...

I have a garage door wall button which has 13.6v across. This is the typical wall button most of us have in the our homes to open and close the garage from inside the house. I want to replace the wall button and connect a ESP8266 IoT chip to control from smart phone and this chip only need...

I`ve bought this board: link to shop (Elecrow ESP8266 ESP-12S A9G GSM GPRS+GPS IOT Node V1.0 Module) Here I`ve read about it: wiki page I would like to use that board with 1inch screen and send data with GSM. I would like to buy LiPoly rechargeable battery for it. I have quite basic electronic...

Hello all, I'm new to this forum but have a question I'd like to see if I can get some answers to and guidance on how to proceed. I have a diy maker project using an ESP8266. In short, it sounds an remote chime and I get a SMS text when a magnetic door switch (reed switch) is opened. I've...

Hi everyone,I have been working this lasts month on a little Arduino project about making a remote control car. I'm using 2 Arduino Uno boards, one for the car and the other for the remote controller. I'm also using the module ESP8266 12-f for sending and receiving orders (I use the AT...

I was reading datasheet of TPL5110 it says "the TPL5110 has a unique One-shot feature where the timer will only power the MOSFET for one cycle." I do not understand what does it mean by "One-shot feature" and "turning on MOSFET for one cycle" here what does it mean by one cycle? I want to turn...

I'm trying to setup interrupt in arduino based environment using board ESP8266-01, based on help i found on different sites i wrote following code, but when i program my device it continuously shows interrupt message "Interrupt Ocurred: 1" on serial monitor, while same program running if i pull...

Hi all, I'm using ESP32 model: ESP8266 with a built in BT module. I'm trying to open a BT connection between the board and an phone app with sending data rate of ~1-3kHz. I'm using Aruino IDE as a code environment and implementing the connection using #include "BluetoothSerial.h" library...

For all with interest in application of the ESP8266 and ESP32 family microcontrollers from Espressif, I would like to reccommend the following project we are working on. Based on Micropython, we havebuilt a basic framework for IoT projects with ESP chips. The framework has out of the box and...
