What do i need to Connect more than 1 servo? I use the SG90 Servo and i want to use 3 of them in total.
Welcome to the forum
Your topic has been moved to a more relevant forum category
You can connect the data lines and GND wires from all 3 servos to an Arduino but you should provide external power for the servos as the Arduino is not designed to be used as a power supply and servos take a lot of current
As to exactly what you should use for the connections, that depends on which Arduino board you are using, your knowledge and experience of electronic circuits and what equipment you have available
It appears you did not look very hard, I found this in about 20 seconds: How to Use Servo Motor (SG90): Pinouts, Specs, and Examples | Cirkit Designer It has a major mistook, Do NOT power it with the Arduino use an external power supply.

Gil's Crispy Critter Rules for Processor Hardware:
- Rule #1: An Arduino is NOT a Power Supply!
- Rule #2: Never connect anything inductive (motors, speakers) directly to an Arduino!
- Rule #3: Avoid connecting or disconnecting wires while the power is on.
- Rule #4: Do not apply power to any pin unless you are certain of what you're doing.
- Rule #5: Do not exceed the maximum voltage ratings.
- Rule #6: Many Arduinos cannot power transmitters directly.
- Rule #7: Before powering your project, take a break and double-check the wiring.
LaryD’s Corollaries:
- Coro #1: When starting out, add a 220Ω resistor in series with both input and output pins to protect against shorts.
- Coro #2: Invest in a Digital Multi-Meter (DMM) to measure voltages, currents, and resistance.
Note: Violating these rules can turn your Arduinos into crispy critters. For optimal performance, keep your wires under 25 cm (10 inches).
Additional Tips:
- The L293 motor driver, though common, is inefficient as it can lose around 3V as heat when driving both legs of a motor. Consider using a motor driver with MOSFET outputs to reduce heat loss and conserve battery power.

I Bought a big kit with everything,I'm using and Arduino Uno. And I'm not that good at this stuff since i Just started i was able to do One servo,but i cant find how to Power the other two.
How did you power the first one ?
My guess is that you used the GND and 5V sockets on the Uno. Am I right ?
Do you have breadboard and wire jumpers ?
Yes,i Have a breadboard and a Lot of jumper wires. What do i do with them?
Best to connect the servo power separately, as breadboards are not designed to handle motor or servo current. The tracks may burn and become unreliable.
You can buy servo power distribution modules. Budget 1 Ampere per small servo (SG-90), 2.5 Amperes per large servo (MG996).
Yes,But How do i connect more than One? Do i connect them to the Power supply?
Yes.
Did you notice the mention of a servo power distribution board? One of many examples. Second example, with controller.
I didn't. Thank you.
