Electronic, 3D printing and embedded programming
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.

Here we are going to see CNC shield, Stepper driver and stepper motor
When you start to create a CNC or something similar you need a stepper motor, probably you can find they inside your trash.
It’s important to understand the stepper motor color code for 4 and 6 wire type.
You may need to program Arduino microcontroller (like) remotely to debug in the freezer.
Here is my solution to the problem.
ESP-01 is low cost esp8266 module, with built-in WIFI.
It was created as Arduino WIFI module, but It’s more powerful than an Arduino, than now if you need a little module to control a relay or some simple digital datalogger It’s the best solution.
I’m going to explain a connection schema for a character display i2c adapter.
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.
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.
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
