Why do the servos turn in opposite directions and not in the same ?
Both the first and the second servo work with that code, but in the opposite direction.
Code:
#include<Servo.h>
int servoPin=9;
Servo Servo0;
void setup(){
Servo0.attach(servoPin);
}
void loop(){
Servo0.write(0);
delay(2000);
Servo0.write(45);
delay(1000);
Servo0.write(90);
delay(1000);
Servo0.write(180);
delay(1000);
}

Are the wires actually displaced in the picture on the blue servo or is that how you have it wired? from left to right it looks like you’re running power, ground then single and the black servo looks like power, signal then ground.
Grounding is related to grounding,
power supply connected to the power supply,
Signal input connected to Signal output pin 9 on Arduino, although colors wires are not common.
Please check whether there is an errors connecting.
In the blue servo, the inputs are arranged like this from left to right: 1. Ground, 2. Power, 3. Signal
In the black servo, the inputs are arranged like this from left to right: 1. Power, 2. Signal, 3. Ground
I tested the servo here www.tinkercad.com, a simulation .brd file was also uploaded, except image.
