Skill Share: Arduino is so 2008, now we do ESP

What is the Arduino anyway?

The first Arduino.jpeg

The Arduino project began in 2005 as a tool for students at the Interaction Design Institute Ivrea, Italy, aiming to provide a low-cost and easy way for novices and professionals to create devices that interact with their environment using sensors and actuators. from

  • ATmega328P, 2KB SRAM, 32KB FLASH, 1KB EEPROM

The Rise of Espressif Systems chips and break-out boards

The ESP8266 is a low-cost Wi-Fi microchip, with built-in TCP/IP networking software, and microcontroller capability, produced by Espressif Systems in Shanghai, China. The chip was popularized in the English-speaking maker community in August 2014 via the ESP-01 module.
