Arduino core 2.2.0 for ESP8266 WiFi chip

#Arduino core for #ESP8266 WiFi chip

This project brings support for ESP8266 chip to the Arduino environment. It lets you write sketches using familiar Arduino functions and libraries, and run them directly on ESP8266, no external microcontroller required.

ESP8266 Arduino core comes with libraries to communicate over WiFi using TCP and UDP, set up HTTP, mDNS, SSDP, and DNS servers, do OTA updates, use a file system in flash memory, work with SD cards, servos, SPI and I2C peripherals.

ESP32 – Next gen ESP8266 from Espressif

#ESP32 – Next gen #ESP8266 from #Espressif

The ESP32 has many improvement. Appart from WiFi support, it also includes a Bluetooth 4.2 radio. The CPU is similar to the ESP8266 – it’s a 32-bit Xtensa® LX6, but the ESP32 has two cores! There’s also 128KB of ROM and 416KB SRAM, but Flash memory (for program and data storage) is still left up to an external chip (up to 64MB).

#HowTo build a WiFi Switch/SmartSwitch using ESP8266, Attiny85 and Android app

#Project #HowTo build a WiFi Switch/SmartSwitch using ESP8266, Attiny85 and Android app

The Wifi Arduino 85 is a small board with ESP8266 -01 module, Attiny85 micro controller and a relay. It Also has and additional header for connecting an external relay or to connect sensors like PIR, IR etc depending on your application. If you are a tinkerer you will also be able to connect a HC-05/06 Bluetooth module and convert this board to a Bluetooth Arduino 85 board.

I am going to make a Swith board using the following ingredients

  1. Wifi Arduino 85 Board (comes with ESP8266 -01 module)
  2. Mobile Charger (5V 1A DC )
  3. PIR Sensor
  4. Plastic Gang Box(4″X7″)
  5. Varistor (270V AC)
  6. Three Pin Socket
  7. Three Pin Plug
  8. Switch
  9. Double sided tape

Apart from this you will need a blade to cut the plastic box and a screwdriver

Lets start building it …

Which #ESP8266 Module is right for you

Which #ESP8266 Module is right for you

The ESP8266 is an amazing chip for all your home automation & Internet of Things projects. This chip costs less than $5, has WiFi connectivity, an onboard processor, and is compatible with the Arduino IDE. I already wrote a guide on how to get started with the ESP8266, but I wanted to dive deeper and answer a fundamental question: how to choose your ESP8266 module?

Indeed, there are many choices available on the market, and it is easy to get lost between all of them. This is why I wrote this guide to help you out choosing your ESP8266 module for your next project. This list is of course non-exhaustive, but these all are modules I tested myself and I was satisfied with. Let’s dive in!

An #eBook #free and #open on #ESP8266 #WiFi module

An #eBook Open on #ESP8266 for #free

“Kolban’s book on the #ESP8266” – This ebook was created by Mr. Neil Kolban and dedicated it to the community.

If you are a beginner  starting with ESP8266 wifi module, then we recommend you this book. It will teach you where and how to begin things.

This book (if we want to call it that) is my collated and polished version of those notes. Rather than keep them to myself, I offer them to all of us in the ESP8266 community in the hope that they will be of some value.
