Servos on serial dont work

Im using a Pololu-1350 Micro Maestro 6-Channel USB Servo Controller . I’ve tried

BLYNK_WRITE(V3) { servo.write(param.asInt()); in setup. Should it be in loop?
How do I “attach” Vpin to a certain servo when they all (6DOF) on RX/TX.? Thnx in advance.

I’d suggest that you start by providing proper information about the hardware you are using this with, how you’re connecting your hardware together, and what sketch you’ve been using to control the hardware without Blynk.


Sorry Wemos D1+Pololu 6 servo driver via (rx/tx) and Pololu maestro control center


#include <Blynk.h>

#define BLYNK_PRINT Serial
#include <PololuMaestro.h>

#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <Servo.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "************************";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "*************";
char pass[] = "***********";

Servo servo;

#define maestroSerial SERIAL_PORT_HARDWARE_OPEN
#include <SoftwareSerial.h>
SoftwareSerial maestroSerial(10, 11);

MicroMaestro maestro(maestroSerial);
//MiniMaestro maestro(maestroSerial);

void setup()
  // Set the serial baud rate.

//Blynk.begin(auth, ssid, pass);
// You can also specify server:
Blynk.begin(auth, ssid, pass, "", 80);
//Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
void loop()

  maestro.setSpeed(0, 0);

  maestro.setAcceleration(0, 0);

  // Set the target of channel 0 to 1500 us, and wait 2 seconds.
  maestro.setTarget(0, 6000);

  // Configure channel 0 to move slowly and smoothly.
  maestro.setSpeed(0, 10);
  maestro.setAcceleration(0, 127);

  // Set the target of channel 0 to 1750 us, and wait 2 seconds.
  maestro.setTarget(0, 7000);

  // Configure channel 0 to go more quickly and smoothly.
  maestro.setSpeed(0, 20);
  maestro.setAcceleration(0, 5);

  // Set the target of channel 0 to 1250 us, and wait 2 seconds.
  maestro.setTarget(0, 5000);
} ```

That doesn’t really answer the question that I asked.
If you don’t want to share the complete details and working non-Blynk code then it seems unlikely that anyone is going to be able to help unless they have first hand experience of this rather unusual hardware combination.


Sorry, appearantly i dont understand, this is all i have. its another board that controls the Roboarms on a robot I built. Code came from example from pololu in Arduino ide. If theres a better way would be great, i m open 4 suggestionCapture

That’s no clearer for me I’m afraid, in fact I’m now more confused.

When you created this topic it asked for various pieces of information, non of which you’ve provided.
As you’re also using some unusual hardware, I asked you for more details about the hardware you are using, and how your hardware is interconnected - something you’ve also not provided.

I’m going to walk away from this discussion, but if you want others to help then I don’t think what you’ve posted so far is going to facilitate that.


Ive provided sketch (u asked 4) ive provided hardware (u asked 4)ive provided control (u asked 4) I cant imagine why you have so much problem. If its “over your head” just say so. Its not unusual,its just new to you. Thnx anyhow another Blynk user knew the solution in another forum.
