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.
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.
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
