Ebyte LoRa E32 device for Arduino, esp32 or esp8266: specs and basic use – 1
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
Start with specs and basic usage.
Send email with esp8266 and Arduino (Library v1.x)
A simple method to notify a problem is to use email, It’s very usefully and simple to share, so I created a library to do It. I get some code from GSender a library that It’s quite simple, but not so complete and configurable.
WeMos D1 mini (esp8266), integrated SPIFFS Filesystem – Part 2
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 (esp8266), pinout, specs and IDE configuration – Part 1
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.
PCF8575 i2c 16 bit digital I/O expander
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.
Voltage divider: calculator and application
Voltage divider It’s a circuit very common in electronic, I add a simple calculator and some application in this article.
PCF8591 i2c Analog I/O Expander
Library to use i2c pcf8591 IC with arduino and esp8266.
This IC can control (until 4) analog input and/or 1 analog output like measure voltage, read thermistor value or fade a led.
Can read analog value and write analog value with only 2 wire (perfect for ESP-01).
I try to simplify the use of this IC, with a minimal set of operation.
PCF8574 i2c digital I/O expander: Arduino, esp8266 and esp32, basic I/O and interrupt – Part 1
Library to use i2c pcf8574 IC with arduino and esp8266.
This IC can control (until 8) 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.
DHT12 i2c Cheap Humidity and Temperature Sensor
This is an Arduino and esp8266 library for the DHT12 sensor, a very low cost temperature/humidity sensors (less than 1$) that work with i2c or one wire connection
