How to connect SG90 micro servo to Arduino Uno?
The connection with Arduino is very straightforward. The servo motor has three wires. The brown one is for ground, so connect it to the Arduino ground.
The red wire is VCC, which typically requires a voltage between 4.8 to 7.2 volts. Therefore, connect it to Arduino 5V.
The last wire, the orange one, is the control signal that needs to be a PWM signal with a period of twenty milliseconds, also known as 50 Hertz
and a duty cycle of one to two milliseconds, which is five to ten percent.
A one-millisecond pulse represents the -90° position of the motor shaft, a 1.5-millisecond pulse indicates the 0° position, and
a two-millisecond pulse corresponds to the +90° position. This allows for a total rotation of 180° of the shaft.
