esp8266

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...

Hi everyone, I’m seeking guidance. I have a tricky situation which I don’t really know how to get out of. I want to design a system which would consume the least amount of power possible. The idea is to have an ESP8266 do a simple task every minute (updating a e-paper display) and sleep the...
