I’m pretty sure that most people reading this very article know about the (very) cheap ESP8266 Wifi module.
A bit more than a year ago, I actually made a small development board for it, which was recently used in the connected lamp that wakes me up. While what follows pales in comparison to what cnlohr has implemented on this chip over the last months, sometimes you just have small projects that you don’t want to spent days on.
Anyway, the ‘standard’ way of compiling programs for this neat little chip involves installing a cross-compiling toolchain on a Linux computer (or VM), and then using a dedicated tool to flash your program to the ESP8266.
As you can guess, this can quickly get tiring if all you want to do is blink an LED… but then I stumbled upon NodeMCU and Domoticz.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
