ESP8266 example: Wi-Fi Access point, static IP, web-server and remote GPIO control

After testing the basic Wi-Fi connectivity options of the ESP8266 it is now time to explore some of the more interesting features of the chip. In the sketch below the NodeMCU development board creates a Wi-Fi access point and starts a web-server. A HTML page hosted on the web-server displays analog data from a photocell and allows you to control… Read More »

NodeMCU: a ESP8266 based low cost IoT board

ESP8266 Introduction The ESP8266 is a low cost MCU with built in Wi-Fi. It can be paired with another host microcontroller, like an Arduino, to provide WiFi networking capability for a basic IoT development platform. Additionally, the ESP8266 can be used as a stand-alone MCU,  as it includes a 32-bit 80Mhz processor, 16 GPIO pins (4 PWM enabled)… Read More »

My first 3D printer: Monoprice Select Mini 3D

After a lot of reading and drooling over various 3d printers, I finally pulled the trigger and got myself one: the Monoprice Select Mini 3D.  This is a budget printer and the design was focused on low price, versus performance and speed. I am not interested in producing large, very artistic, or decorative prints, so this is… Read More »

Win the new Arduino MKR1000 32bit Wi-Fi enabled IoT board

The “World’s Largest Arduino Maker Challenge” is happening right now through a partnership between Hackster.io, Atmel, Adafruit, Arduino and Microsoft. Here is a video presentation of the context by Massimo Banzi, CEO of Arduino.cc: The contest will run in multiple phases, the first being an idea submission, by January 15th, 2015. A 1,000 lucky makers… Read More »
