I use:
Arduino Leonardo
Arduino Wireless SD Shield
XBEE USB Adapter
Two XBEE S1

Receive from Button State was OK, but no sending (LED turn on/off). What's wrong with code?

Code:

#include <SoftwareSerial.h>

const int buttonPin = 2;
const int ledPin = 13;

int buttonState = 0;

SoftwareSerial xbee (0,1);

void setup() {
  xbee.begin(9600);
  pinMode(ledPin, OUTPUT);
  pinMode(buttonPin, INPUT);
}

void loop(){
       
  if (xbee.available() >0 )
  {
    char ch = xbee.read();
    if (ch == '1')
    {
      digitalWrite(ledPin, HIGH);
    }
    else if (ch == '0')
    {
      digitalWrite(ledPin, LOW);
    }
  }
  buttonState = digitalRead(buttonPin);
 
  if (buttonState == HIGH) {
    xbee.println("Button pressed!");
    delay(500);
  }
}
   
   

[XBEE PRO S1]

Hello,

i've 3 XBEE PRO S1 (XBP24-ACI-001 revG). Original Firmware is XBP24

I want flash the Firmware XBP24-B. Howewer, i got error message. Why?

I want set COORDINATOR and ROUTER.

Nothing works. I give up!

If i remove while(1), Roverbot turn left around and can stopped it, but not follow the line.

If i set while(1), Roverbot follow the line and can't stopped it.

What the heck????

This sucks!

OMG! This sucks!

[This Code without Serial works, Roverbot follow the black line.]

Hello all,

i use the Lego Roverbot with Line Tracking Sensor for Arduino


This Code without Serial works, Roverbot follow the black line.

Code:

void loop() {
start_line_follow();
  }

void start_line_follow() {
  if (digitalRead(10) == HIGH) {
  Motor1(255, false);
  Motor2(255, true);
 }
 else
 {
  Motor1(255, true);
  Motor2(255, true);
  return;
 }
}
}

This Code with Serial doesn't works, Roverbot turn left around, but not follow the line.
0 = Stop Line Follow
1 = Start Line Follow

Code:

void loop() {
  if (Serial.available() > 0) {
    incomingData = Serial.read();
   
    if (incomingData == 49) { // ASCII Code for 1
      start_line_follow();
    }
   
    if (incomingData == 48) { // ASCI Code for 0
      stop_line_follow();
    }
  }
}

void start_line_follow() {
  if (digitalRead(10) == HIGH) {
  Motor1(255, false);
  Motor2(255, true);
 }
 else
 {
  Motor1(255, true);
  Motor2(255, true);
  return;
 }
}

void stop_line_follow() {
  Motor1(0, false);
  Motor2(0, false);
  return;
}

Code:

int ledPin = 13;

void setup() {
  pinMode(ledPin, OUTPUT);
  }

void loop() {
  for(int fadeValue = 0; fadeValue <= 255; fadeValue++) {
    analogWrite(ledPin, fadeValue);
    delay(5);
  }
  for(int fadeValue = 255; fadeValue >= 0; fadeValue--) {
    analogWrite(ledPin, fadeValue);
    delay(5);
  }
}

Why is ledPin 13 blinking, not fading? I use Arduino UNO R3.


int ledPin = 2; -> Blink
int ledPin = 3; -> Fade
int ledPin = 4; -> Blink
int ledPin = 5; -> Fade
int ledPin = 6; -> Fade
int ledPin = 7; -> Blink
int ledPin = 8; -> Blink
int ledPin = 9; -> Fade
int ledPin = 10; -> Fade
int ledPin = 11; -> Fade
int ledPin = 12; -> Blink
int ledPin = 13; -> Blink

[until]

Right button pressed -> Right LED blinking until Right button pressed -> Right LED off
Left button pressed -> Left LED blinking until Left button pressed ->  Left LED off

It's blinking, but not turn off Pls help

Here Code:

Code:

int button_right = 2;
int button_left = 3;
int led_right = 5;
int led_left = 6;

int buttonState_right = 0;
int buttonState_left = 0;

void setup()
{
  pinMode(button_right, INPUT);
  pinMode(button_left, INPUT);
  pinMode(led_right, OUTPUT);
  pinMode(led_left, OUTPUT);
  Serial.begin(9600);
}

void loop()
{
  buttonState_right = digitalRead(button_right);
  buttonState_left = digitalRead(button_left);
 
  if (buttonState_right == HIGH) // First Right Button pressed
  {
   Blinking_right(HIGH);
  }
   
  if (buttonState_right == HIGH) // Second Right Button pressed
  {
   while (Blinking_right)
   {
    Blinking_right(LOW);
   }
  }
 
   if (buttonState_left == HIGH) // First Left Button pressed
  {
   Blinking_left(HIGH);
  }
   
  if (buttonState_left == HIGH) // Second Left Button pressed
  {
   while (Blinking_left)
   {
    Blinking_left(LOW);
   }
  }
 }

void Blinking_right(boolean right) {
  digitalWrite(led_right, HIGH);
  delay(300);
  digitalWrite(led_right, LOW);
  delay(300);
}

void Blinking_left(boolean left) {

Hi,

i have this Motor Controller from DFRobot

How did it?

Here the code.

[How can i change PWM speed Motor while Button click? Slow = 50 ; Fast = 255]

Hello,

I use Visual Basic 2010 to control my Lego Robot. It works.

How can i change PWM speed Motor while Button click? Slow = 50 ; Fast = 255

Arduino Code http://www.dfrobot.com/wiki/index.php?title=Arduino_Motor_Shield_%28L293%29_%28SKU:_DRI0001%29

Code:

case 'w'://Move ahead
                        Motor1(255,true);  //You can change the speed, such as Motor(50,true)
                        Motor2(255,true);
                         break;

Visual Basic 2010 Code

Code:

Private Sub slowButton_Click(sender As System.Object, e As System.EventArgs) Handles slowButton.Click
        SerialPort1.Write("1")
        slowButton.BackColor = Color.Yellow
        fastButton.BackColor = Color.Transparent
    End Sub

    Private Sub fastButton_Click(sender As System.Object, e As System.EventArgs) Handles fastButton.Click
        SerialPort1.Write("2")
        slowButton.BackColor = Color.Transparent
        fastButton.BackColor = Color.Yellow
    End Sub
