Electronic, 3D printing and embedded programming
Serial Peripheral Interface Flash File System, or SPIFFS for short. It’s a light-weight file system for microcontrollers with an SPI flash chip. The on-board flash chip of the ESP8266 has plenty of space for your files.
WeMos D1 mini, a little guide to use this low cost but powerful microcontroller with WIFI integrated.
Specification and IDE configuration to start use It.
Summer work for my wife, a little lantern with led and removable battery
I’d like to share some pics of my current work. New board for my Ciclop 3D scanner, in the next week I’d like to share the tutorial on how to build It.
I really like the ATtiny and programming it, so I built a simple board to use Arduino UNO as ISP in a faster way.
Library to use i2c pcf8575 IC with arduino and esp8266.
This IC can control (until 16) digital devices like button or led with 2 only pins.
Can read and write digital value with only 2 wire (perfect for ESP-01).
I try to simplify the use of this IC, with a minimal set of operation.
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer (competitor bmp280, DHT11, DHT22, Dallas and thermistor).
Finally the comparison.
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer (competitor bmp280, DHT11, DHT22, Dallas and thermistor).
Today the code to get sensors fully working.
I’m going to create the famous Ciclop 3D Scanner, but my first problem is how to get round plexiglass base, but the costs is too expensive. So I decided to design a printable one.
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer, and introduce the competitor bmp280, DHT11, DHT22, Dallas and thermistor.
Today the specification of the sensors I use.
