Esp8266 wifi Weather Monitoring Temperature Pressure, Humidity,& Altitude.

Esp8266,Dht11,Dht22,to Monitor Temperature Pressure,humidity,& Altitude

download our free Arduino stepper control code and read the code carefully, then read all pins where to connect in our case steps pin is 8, direction pin is 9 and enables pin is 10 and potentiometer input pin is A0 (variable voltage signal) respectively.

how its work.

. first, upload the code into Arduino or Arduino mega then need to connect all connections than on the power supply and increase speed first using a potentiometer to start operation then toggle button to change direction .you also used sensor instead of the button.

#include // defines pins numbers

const int stepPin = 8;

digitalWrite(enPin,LOW);

// Set Dir to Home switch

digitalWrite(dirPin,HIGH); // Enables the motor to move in a particular direction }

// read the sensor value:

int sensorReading = analogRead(A0);

// map it to a range from 0 to 100:

int motorSpeed = map(sensorReading, 0,1023,1,100);

// set the motor speed:

if (motorSpeed > 0) {

myStepper.setSpeed(motorSpeed);

// step 1/100 of a revolution:

myStepper.step(stepsPerRevolution /400);
