Reading Potentiometer in ROS
Hey Folks,
I am trying to read potentiometer value in ROS, but I stuck with error
#include <ros.h>
#include <ros/time.h>
/*
AnalogReadSerial
Reads an analog input on pin 0, prints the result to the serial monitor.
Graphical representation is available using serial plotter (Tools > Serial Plotter menu)
Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
This example code is in the public domain.
*/
// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// print out the value you read:
Serial.println(sensorValue);
delay(1); // delay in between reads for stability
}
To be honest, sometimes I don't understand why baudrate is not mentioned in ROSlib. or what the right code I should write for receiving analog signal.
Best, Marwa
You forgot to actually describe your problem. What happens? What should happen? Which error message do you get?
Also: even though
ros.his included in the code snippet, nothing ofrosserialis used here, so this code cannot communicate with the PC side ofrosserialat all.rosserialacts as a bridge, it isn't a generic connect-whatever-to-a-serial-port-and-it-will-work library.
