The Human: Servo Motor and Potentiometer Circuit is a fundamental project that involves creating a simple control system using a microcontroller, a servo motor, and a potentiometer. This tutorial will guide you through the process of building this circuit and demonstrate how it can be used in various applications. To begin with, let's identify the components required for this project: * Microcontroller (e.g., Arduino) * Servo Motor * Potentiometer * Breadboard or PCB * Jumper Wires The next step is to connect the servo motor and potentiometer to the microcontroller. Connect the positive leg of the servo motor to digital pin 9 on the Arduino, while connecting the negative leg to a ground pin. Similarly, connect one end of the potentiometer to analog input A0 on the Arduino, ensuring that the other end is connected to a ground pin. With all connections made, it's time to write the code for this project. Open the Arduino IDE and create a new sketch. Include the Servo library by adding the following line at the top of your code: #include <Servo.h> Next, declare a servo object called "myServo" and initialize it with the pin number where the servo motor is connected. Servo myServo; int servoPin = 9; In the setup() function, attach the servo to the specified pin using the following line of code: myServo.attach(servoPin); Now that the setup is complete, we can move on to the main loop. Here, we'll read the analog value from the potentiometer and use it to control the position of the servo motor. int potValue = analogRead(A0); int servoPosition = map(potValue, 0, 1023, 0, 180); The map() function is used to scale the potentiometer's analog value to a corresponding angle for the servo. In this case, we're mapping the range of 0-1023 (analog values) to 0-180 degrees (servo position). With the servo position determined, we can now move it to that specific location using the following line of code: myServo.write(servoPosition); Finally, delay() for a short period of time to allow the servo to settle into its new position. delay(15); And that's it! With this project, you've successfully created a simple control system using a microcontroller, servo motor, and potentiometer. This circuit can be used in various applications such as robotics, automation, or even art installations.
