Arduino code for adjusting sweep

[JCOLE]

I am making a DIY sea sweep to control powerheads. I am new to Arduino but figured out the setup for the sweep on the servo. Is there a way to add a potentiometer that will allow me to adjust the speed of the sweep? I can adjust the speed in the code but cannot find code for the potentiometer. Any help would be greatly appreciated.

Hey brother the Free version of Chatgpt is very good at coding. Thank me later but test it out.

You can definitely add a potentiometer to your Arduino setup to adjust the speed of the servo sweep. A potentiometer can be used to provide a variable input that you can read with the Arduino's analog input pins. You can then use this input to adjust the speed of the servo sweep in your code. Here’s a basic example of how you can do this:

Hardware Setup​

1. Connect the middle pin of the potentiometer to one of the Arduino's analog input pins (e.g., A0).
2. Connect one of the other pins of the potentiometer to 5V.
3. Connect the remaining pin of the potentiometer to GND.

Code Example​

Here’s an example sketch that demonstrates how to read the potentiometer value and use it to control the speed of a servo sweep:
cpp
Copy code
#inc#includervo.h>

Servo myservo; // create servo object to control a servo

int potPin = A0; // analog pin used to connect the potentiometer
int potValue; // variable to read the value from the analog pin
int servoPin = 9; // digital pin connected to the servo
int delayTime; // variable to adjust delay time based on potValue

void setup() {
myservo.attach(servoPin); // attaches the servo on pin 9 to the servo object
}

void loop() {
potValue = analogRead(potPin); // reads the value of the potentiometer (value between 0 and 1023)
delayTime = map(potValue, 0, 1023, 50, 1000); // scale it to a range that suits your needs (e.g., 50 to 1000 milliseconds)

myservo.write(0); // set servo to 0 degrees
delay(delayTime); // wait for the delay time

myservo.write(180); // set servo to 180 degrees
delay(delayTime); // wait for the delay time
}

Explanation​

• analogRead(potPin) reads the value from the potentiometer, which will be between 0 and 1023.
• map(potValue, 0, 1023, 50, 1000) scales the potentiometer value to a range suitable for your delay time. You can adjust the range (50 to 1000 milliseconds) based on how fast or slow you want the sweep to be.
• The servo moves between 0 and 180 degrees with a delay between movements based on the potentiometer value.

This is a simple example. You might need to adjust the code based on your specific requirements and the range of speeds you want to achieve.

Perfect. Gotta love AI! I will try this out tonight. Thank you.
