I uploaded Tasmota onto a Wemos D1 and I am testing it's possibilities and capabilities.
I would like to control SG90 servos via MQTT connected to an IIC I²C PCA9685 servo controller.
I am curious on how this works over wlan.
It is just that I am not overly experienced with these kind of things but would like to learn more.
How can I change this program to adress the servos over MQTT and IP?
They are connected to the D1 mini via D1 GPIO5 SCL and D2 GPIO4 SDA
Here is a link to the Servo Control With PCA9685 and Arduino

Code:
#include <Adafruit_PWMServoDriver.h>
Adafruit_PWMServoDriver board1 = Adafruit_PWMServoDriver(0x40); // called this way, it uses the default address 0x40
#define SERVOMIN 125 // this is the 'minimum' pulse length count (out of 4096)
#define SERVOMAX 625 // this is the 'maximum' pulse length count (out of 4096)
void setup() {
Serial.begin(9600);
Serial.println("16 channel Servo test!");
board1.begin();
board1.setPWMFreq(60); // Analog servos run at ~60 Hz updates
}
void loop()
{ for(int i=0; i<8; i++)
{ board1.setPWM(i, 0, angleToPulse(0) );}
delay(1000);
for( int angle =0; angle<181; angle +=10)
{ for(int i=0; i<8; i++)
{ board1.setPWM(i, 0, angleToPulse(angle) );}
}
delay(100);
}
int angleToPulse(int ang) //gets angle in degree and returns the pulse width
{ int pulse = map(ang,0, 180, SERVOMIN,SERVOMAX); // map angle of 0 to 180 to Servo min and Servo max
Serial.print("Angle: ");Serial.print(ang);
Serial.print(" pulse: ");Serial.println(pulse);
return pulse;
}
