• Best Stepper Driver

I purchased the Adafruit Motor Hat and a stepper motor and am trying to get the motor working. I followed their tutorial for installing software found here, and tried running their example code called StepperMotor.py.

About NodeMCUNodeMCU is a very popular Micro controller with wifi access. It is based on ESP8266 – a cheap but powerful chip and fully support Arduino IDE.

If you familiar with Arduino IDE, you can program NodeMCU in no time.Objective:In this project, we will connect a step motor to a NodeMCU chip, then use a MQTT client(mobile app, browser, linux terminal program etc) to send signal to NodeMCU to control the motor rolling. When MQTT client send message “1”, Step motor will make clockwise rolling. When MQTT client send “0”, motor will make counter-clockwise rolling.A ULN2003 motor drive module will connected between NodeMCU and step motor.
