Electronics, Programming, 3D Printing, and Embedded Systems Tutorials
When you use a microcontroller an important features is store data, for logging or setting, for a web server or to show image. The better solution is an SD card, because It’s simple, small and low power device.
Now we are going to look how to connect and use with standard SD library with Arduino and esp8266.
When you create a new IoT project probably you need to connect microcontroller to a battary power source, but if you don’t use a power saving options your battery will run out in no time.
As a lot of IoT microcontroller, WeMos D1 mini have some power saving mode.
The types are modem sleep, light sleep and deep sleep.
WeMos D1 mini have 2 UART, one on dedicated pins and a transmit-only UART that can be enabled on GPIO2 (D4), It’s very usefully for debug.
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.
I really like the ATtiny and programming it, so I built a simple board to use Arduino UNO as ISP in a faster way.
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.
