Limpkin writes: I usually never use libraries… but made an exception for these quick projects ! 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 […]
Patrik Thalin writes: This device is installed in my home to monitor the usage of electricity. It counts the pulses from the meter and produces a log file with number of pulses and a time stamp that can later be analyzed. The hardware is quite simple. The NodeMCU development kit board with an ESP8266 running […]
@PixelatedPic tweeted, “IoT with ESP8266 + NodeMCU firmware and couple of Lua :) its alive!”
Ray Wang from RaysHobby has written an article on his ESPToy 1.2, a ESP8266 development board based on the Lua firmware: A little while back I released the very first version of ESPToy — a ESP8266 Development Board with a few useful on-board components like color LED, button, and temperature sensor. It has a built-in […]
Markus Gritsch shared his WiFi LED light project in the forum: I built a prototype for a WiFi controllable LED light, using the popular ESP8266 module running the NodeMCU firmware . To allow controlling the WS2812B LEDs from Lua, I extended the firmware with a bit of C code Check out the video after the break.
doub posted an update on his Lua board we covered previously: Today I soldered a second one, and it looks much better. Here is a picture. I just plugged it on my PC while pressing the DFU button and Windows recognized it as a “STM Device in DFU Mode”, and properly downloaded the drivers, so […]
doub has been working on a development board for Lua programming: So this project is about packing a relatively fast microcontroller, but not complex enough to require a high level OS (like Linux for SoC-class chips), with a big RAM chip. I picked a STM32F427, because I have some experience with the STM32 family, the core […]
