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 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
