Slider Problem on dashboard

Community Help With My Project Helped
1

Hello,

I working on a project about using a stepper motor to open a greenhouse window, but i can’t add a digital slider on dashboard.

Hardware : ARDUINO MEGA 2560 REV3 with W5100 ethernet shield

Code it’s from a post of cayenne community:

//#define CAYENNE_DEBUG // Uncomment to show debug messages
#define CAYENNE_PRINT Serial // Comment this out to disable prints and save space

#include <CayenneDefines.h>
#include <BlynkSimpleEsp8266.h>
#include <CayenneWiFiClient.h>
#include <ESP8266WiFi.h>

//define stepper pins
#define DIR_1 12
#define DIR_2 13
#define STEP_1 14
#define STEP_2 16

// Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
char token = “token”; //your token

// Your network name and password.
char ssid = “ssid”; //your ssid
char password = “pass”; //your pass

//step direction globals
int step_direction_1 = 0;
int step_direction_2 = 0;

void setup() {

//setup your stepper pins as outputs
pinMode(DIR_1, OUTPUT);
pinMode(STEP_1, OUTPUT);
pinMode(DIR_2, OUTPUT);
pinMode(STEP_2, OUTPUT);

Serial.begin(9600);
Cayenne.begin(token, ssid, password);
}

void step_one(int dir, int steps) {
step(step_direction_1, STEP_1, dir, steps);
}

void step_two(int dir, int steps) {
step(step_direction_2, STEP_2, dir, steps);
}

void step(int dir_pin, int step_pin, int dir, int steps){

digitalWrite(dir_pin,dir);

delay(50);

for(int i=0;i<steps;i++){
digitalWrite(step_pin, HIGH);
delayMicroseconds(100);
digitalWrite(step_pin, LOW);
delayMicroseconds(100);
}
}

void loop()
{
Cayenne.run();
}

//get step direction from dashboard (stepper 1)
CAYENNE_IN(V1)
{
step_direction_1 = getValue.asInt();
}

//step number of steps in slider on stepper 1
CAYENNE_IN(V2)
{
step_one(step_direction_1,getValue.asInt());
}

//get step direction from dashboard (stepper 2)
CAYENNE_IN(V3)
{
step_direction_1 = getValue.asInt();
}

//step number of steps in slider on stepper 2
CAYENNE_IN(V4)
{
step_two(step_direction_2,getValue.asInt());
}

Problem is when i want to add digital widget as slider i only can add analog :slight_smile:

I did something wrong?

Thanks

this code is of old cayenne. you need to use new MQTT cayenne library. GitHub - myDevicesIoT/Cayenne-MQTT-Arduino: Cayenne MQTT Arduino Library

Yes sir,

you want to add a digital button or a slider?

5

I want to use a slider for stepper direction

6

then it will be a analog actuator. the slider position will control the position of stepper motor.

7

So, any support for add a stepper motor in future? I use that sketch found on community forum but don’t work for me :slightly_smiling_face:

8

it is already supported. you need to code your Arduino accordingly to so that it works with cayenne.
what is that you are trying to do with stepper motor and cayenne?

9

Going to use Cayenne for my hobby greenhouse, have a lot of sensors up and running at this moment.

1 x YF-S401 ( to have status on how much water need for last irrigation )
2 x relay ( pump & light )
1 x DS18B20 ( for water temperature )
1 x AM2301 ( greenhouse temp & hum )
1 x DHT11 ( outside temp & hum )
1x BMP180 ( temp & pa )
1 x HC-SR04 ( water level in basin )

I need a code for a NEMA 17 with axe for greenhouse window, never used a stepper motor. If i can’t find a proper code maybe i will buy a servomotor instead.
I draw something in paint :smirk:

10

first get the code working for your stepper motor without cayenne and then share here.

11

I try that code

// defines pins numbers
const int stepPin = 10;
const int dirPin = 11;

void setup() {
// Sets the two pins as Outputs
pinMode(stepPin,OUTPUT);
pinMode(dirPin,OUTPUT);
}
void loop() {
digitalWrite(dirPin,HIGH); // Enables the motor to move in a particular direction
// Makes 200 pulses for making one full cycle rotation
for(int x = 0; x < 5000; x++) {
digitalWrite(stepPin,HIGH);
delayMicroseconds(500);
digitalWrite(stepPin,LOW);
delayMicroseconds(500);
}
delay(10000); // One second delay

digitalWrite(dirPin,LOW); //Changes the rotations direction
// Makes 400 pulses for making two full cycle rotation
for(int x = 0; x < 5000; x++) {
digitalWrite(stepPin,HIGH);
delayMicroseconds(500);
digitalWrite(stepPin,LOW);
delayMicroseconds(500);
}
delay(10000);
}

But it’s with delay and automated, i need to control by myself and use a trigger with.

12

Just a simple code like this should work. Add a button on dashboard with channel 1.

CAYENNE_IN(1)
{
int x = getValue.asInt();
if (x == 1){
digitalWrite(dirPin,HIGH); // Enables the motor to move in a particular direction
// Makes 200 pulses for making one full cycle rotation
for(int x = 0; x < 5000; x++) {
digitalWrite(stepPin,HIGH);
delayMicroseconds(500);
digitalWrite(stepPin,LOW);
delayMicroseconds(500);
}
delay(10000); // One second delay

digitalWrite(dirPin,LOW); //Changes the rotations direction
// Makes 400 pulses for making two full cycle rotation
for(int x = 0; x < 5000; x++) {
digitalWrite(stepPin,HIGH);
delayMicroseconds(500);
digitalWrite(stepPin,LOW);
delayMicroseconds(500);
}
}
}
13

I need to use a slider for direction, to open/close the window when trigger temperature sensor.

14

any specific reason to use a slider in your case?

15

No really a reason, i can use 2 button for each direction… tested that code but it don’t work:upside_down_face:

16

Ok it seems that i have a hardware issue, it’s working now but from any reason he get hot, what can be?

17

read this Stepper motors getting HOT! - Motors, Mechanics, Power and CNC - Arduino Forum

18

Ok, i made 2 buttons Open/Close, now i see something strange about motor, when is idle make some tiny rotation, that can be a code problem?

19

follow this tutorial and see if it works http://www.mrhobbytronics.com/arduino-stepper-motor-control/.
if it works without any issue then add the cayenne code.
