how to control a servo motor with a potentiometer
I already did that
sorry I didn’t explain it right
#include <Servo.h>
Servo myservo;
int val;
void setup() {
myservo.attach(9);
}
void loop() {
val = analogRead(1);
val = map(val, 0, 1023, 0, 180);
myservo.write(val);
delay(1);
}
is this supposed to work because the servo just turns by itself randomly and won’t listen tom the potentiometer
did I do everything right
- Show us good images of your actual wiring.
okay
Trey the Servo library's "Knob" example:
- See time @ 19:00
You are using pin A1 so your code shd be something like this:
val = analogRead(A1) //Not analogRead(1)
Yes, the code works. Your wiring, or your power supply, is not correct.
I just wanted how did you get the code working cuz it didnt work when I tried. It worked only after i made a couple of changes. Basically instead of reading from 1 I was reading from A1 for the potentiometer.
Also I think it is advisable to test the components individually.
For the potentiometer could you pls upload real pictures. Also if your wiring is identical to the diagram, you wont get a reading from the potentiometer because the potentiometer and the wires are on different side of the breadboard.
The mistake may be this:
The correct wiring would be something like this:
Also separately test the servo but i do suspect that the issue is with potentiometer.
Connected the components correctly, compiled and uploaded the code... I might have edited the "A1" but I do not remember doing that.
