Pololu Mini Maestro 12-Channel USB Servo Controller

/*
To use the Pololu Mini Maestro 12-Channel USB Servo Controller with an Arduino, you can communicate with the servo controller using serial communication. This example assumes you're using the Pololu Mini Maestro's TTL serial interface to communicate with your Arduino.

First, connect the Mini Maestro to your Arduino as follows:

Connect the Mini Maestro's GND pin to the Arduino GND pin.
Connect the Mini Maestro's TX pin to the Arduino RX pin (pin 0).
Connect the Mini Maestro's RX pin to the Arduino TX pin (pin 1).
Note: Disconnect the TX and RX pins when uploading code to your Arduino to avoid serial communication conflicts.

Now, upload the following code to your Arduino:

This code initializes the serial communication with the Mini Maestro 12-Channel USB Servo Controller using the Arduino's hardware serial pins (TX and RX). In the loop(), the servo connected to channel 0 of the Mini Maestro is moved between positions 1000 (about 0 degrees) and 6000 (about 180 degrees) with a 1-second delay between each movement.

The setTarget() function sends the appropriate command to the Mini Maestro to set the target position of the specified servo.

Please note that this example uses the Arduino's hardware serial pins (TX and RX). You can also use other pins and the SoftwareSerial library if you need to use the hardware serial pins for other purposes, such as connecting an additional device or debugging.

After uploading the code to your Arduino, the servo connected to channel 0 should move between two positions every second. You can modify the code to control other servos or use sensor inputs to adjust the servo movements according to your project requirements.
