Testing a Servo Motor with a Servo Motor Tester | Manual and Arduino-Controlled Setup

In this video, I demonstrate how to test a servo motor using a servo motor tester equipped with two pushbuttons. The tester has VCC, GND, and SIG pins for the servo motor side, and VCC and GND pins for power input.

How to Use the Servo Motor Tester
The servo motor tester allows easy control over the servo without any programming. Just connect:

Power: VCC and GND on the tester to a 5V external power supply.
Servo: Connect the SIG (signal) pin on the tester to the control pin on the servo, and VCC and GND on the servo to the same 5V supply.
You can use the tester buttons to control the servo manually.

Optional: Using an Arduino Uno
If you'd like to control the servo with an Arduino instead:

Connect the servo motor directly to an Arduino PWM pin (e.g., D9), skipping the tester.
Program custom movements with simple Arduino code.
