DFPlayer Mini Makes my Servo Move at Arduino Startup???
Account cancelled 2021-11-19 06:19:37 670 Views0 Replies Hello Everyone,
I have the DFPlayer Mini and am trying to use my Arduino Mega to play a few sounds and make a servo move with the use of a button. Everything works just the way I want it to, however whenever I plugin the Arduino the servo moves 60 degrees one direction and back again. The servo was not doing this until I added the DFPlayer code.
Any assistance would be greatly appreciated.

Code: Select all
#include <Servo.h>
#include <SoftwareSerial.h>
#include <DFRobotDFPlayerMini.h>
Servo Myservo; // create servo object to control a servo
// twelve servo objects can be created on most boards
int pos = 10; // variable to store the servo position
// Use pins 2 and 3 to communicate with DFPlayer Mini
static const uint8_t PIN_MP3_TX = 19; // Connects to module's RX
static const uint8_t PIN_MP3_RX = 18; // Connects to module's TX
SoftwareSerial softwareSerial(PIN_MP3_RX, PIN_MP3_TX);
// Create the Player object
DFRobotDFPlayerMini player;
void setup() {
pinMode(8,INPUT);
Myservo.attach(9); // attaches the servo on pin 9 to the servo object
// Init USB serial port for debugging
Serial.begin(9600);
// Init serial port for DFPlayer Mini
softwareSerial.begin(9600);
// Start communication with DFPlayer Mini
(player.begin(softwareSerial));
// Set volume to maximum (0 to 30).
player.volume(25);
// Play the first MP3 file on the SD card
player.play(1);
}
void loop()
{
if(digitalRead(8)==LOW){
player.play(2);
Myservo.write(30); //ending position of arm to the back of bee, higher the number futher back toward the bee it will go. 11 - 30 only.
delay(2000);
Myservo.write(10); //ending position of the arm to the front of bee, higher the number futher back toward the bee it will go. 29 to 10 only.
delay(2000);
Myservo.write(30);
delay(2000);
}
else
Myservo.write(0);
}
