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.

ATtiny Programmer Board (ArduinoUNO As ISP)
I really like the ATtiny and programming it, so I built a simple board to use Arduino UNO as ISP in a faster way.
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.
Temperature humidity sensors comparison (Data) Part 3
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.
Temperature humidity sensors comparison (Code configuration) Part 2
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.
Temperature humidity sensors comparison (Specifications) Part 1
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.
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.
CNC Cyclone PCB Factory: settings and tests – Part 7
I’d like to renew my cnc for PCB so I decide to create new one from an existing project named Cyclone PCB Factory.
Firmware configuration and milling process.
CNC Cyclone PCB Factory: control panel and bluetooth – Part 5
I’d like to renew my cnc for PCB so I decide to create new one from an existing project named Cyclone PCB Factory.
Control panel and bluetooth connection for wireless control.
CNC Cyclone PCB Factory: probe and relay – Part 4
I’d like to renew my cnc for PCB so I decide to create new one from an existing project named Cyclone PCB Factory.
Here we’re going to see how reduce noise on probe helper and add a relay to activate rotary tool.
