Hi, I would like to use arduino and to control a servo with a slider by bluetooth. Is it possible?
Yes. Welcome to the Blynk forums. Please take the time to read the Documents, Help Center and Sketch Builder - All at the Top Right of this page.
For example, as per the Sketch Builder…
Also search this forum for a few keywords like servo, slider, etc… and you will find a few other servo code examples.

Thanks, your code work but now i want to control five servos. I change the code like this
#include <Servo.h>
Servo shoulder1;
Servo shoulder2;
Servo elbow;
Servo clamp1;
Servo clamp2;
#define BLYNK_USE_DIRECT_CONNECT
#include <SoftwareSerial.h>
SoftwareSerial DebugSerial(0, 1); // RX, TX
#define BLYNK_PRINT DebugSerial
#include <BlynkSimpleSerialBLE.h>
char auth[] = "881947933d3341d68a2a74e48595eec2";
BLYNK_WRITE(V1)
{
shoulder1.write(param.asInt());
}
BLYNK_WRITE(V2)
{
shoulder2.write(param.asInt());
}
BLYNK_WRITE(V3)
{
elbow.write(param.asInt());
}
BLYNK_WRITE(V4)
{
clamp1.write(param.asInt());
clamp1.write(180-param.asInt());
}
void setup()
{
shoulder1.attach(8);
shoulder2.attach(6);
elbow.attach(10);
clamp1.attach(4);
clamp2.attach(12);
// Debug console
DebugSerial.begin(9600);
// Blynk will work through Serial
// Do not read or write this serial manually in your sketch
Serial.begin(9600);
Blynk.begin(Serial, auth);
}
void loop()
{
Blynk.run();
}
But when i control my servos, they are all moving. Could you give me a code that makes my 5 servos work please?
