Hi Luke

Thanks for the reply its been a while my apologies i dont know if you would be interested i have more information on the project.
give me a buzz please then we can chat, have a great day.

Hi there

Does any body have a diagram for the fan sensor ?

Thanks

Hi Masterice

Its wonderful to see what you have put together yes well the display and a added controller would be ok ,maybe a mega 2560 controller and a 128x 64 lcd  would do the trick ?
No worries i know projects sometimes can be longer than expected...

Keep me up to date  ,anything you have diagrams whatever it is ..i could even do some testing if needed " hehe"

Chat soon
Have a good thursday

It would be nice to see what you have put together already give me a shout if you around   :-)

Thanks Tanky

That diagram will work well for me !! you saved the day ... :-)

Hi Tanky

do you have a diagram it would be nice to see what you have put together i dont plan to go the way of making my own as its all Smd  i suppose and im limited in that sense ..

Paul would i be able to get this controller
http://www.seeedstudio.com/wiki/Grove_-_I2C_Motor_Driver_V1.3
bu just ommiting the centre taps of the coils and connecting the " outsides " of each pair of coils ?

Hi Paul

The stepper motor details - 6 wires (japan motor co-  kp56LM2-097- UNIPOLAR)
I would be having two of those steppers each with a optical switch for "home position" connected via I2C.
Ideally be able to adjust the address
Master controller - Mega 2560 connected via I2C
Slave controller - Arm LPC2478 Dev Board with Ethernet and 7" TFT Touch Screen via I2C
Thats all i plan to be having on the wire bus for now .

Hope that helped

Hi there

I have been looking for a simple driver interface with a controller on it that has its own address and uses i2c for coms.
Have looked at various options like the easy driver  but trying to cut down on the amount of wires needed for comms  to and from the  main arduino MCU.

Stepper motor used is nema 23 with 1 home switch there will be various sensors on the i2c bus so i need to be able to assign
a address to the driver ..

Any suggestions

Thanks

Hi there

Looking for someone with ham radio back round that can help out making some modifications and additions  to some code i have for a mega controller  based on a project http://www.qsl.net/on7eq/projects/arduino_ant_matrix.htm


Willing to pay you for the coding .. :-)


Give me a shout  via my email address

Thanks

I am willing to throw in a few dollars for some beers ..for the one that can modify the code slightly for me :-)

Well codding is not my strong point but maybe someone out there would be willing to help out.

Much appreciated

Hi Paul

Thanks for the message .Would anybody be so kind to help me with modifying the code mentioned above so that i can have the 3 separate counter with there respective triggers ...instead of just one channel

I am not a coder but would just modifing the loop and void areas i cannot do.

Anything would be appreciated

Thank you

Hi There

I would like to know if any of you brilliant guys out there could help me get this code to do the following ..
What i would like to have is 3 separate binary counters (4 bits) with 3 separate triggers respectively
1 trigger = 4 bits (3 triggers =12 bits ) ...so that the binary counter moves up on binaries and starts back at 0000 and so on with each of the separate "channels"
I have found this code but need it modified for three instances of the same thing for a mega 2560  arduino
I would be able to throw in a few beers for someone who could modify this excisting code for me thanks

Code:
/*
How do you make 4 LED's count by 1 up to 15? Use Binary!
  first LED = 1
 second LED = 2
  third LED = 4
 fourth LED = 8
To find out the total just add up all the values

We're going to use a byte to represent the number of times the push button has been pressed because we can then loop trhough that byte and light up a coresponding LED.
The reason that binary counting is great is because it's compact. If we try to count in decimal we would need 15 LEDs and use up 15 pins on the arduino
To be able to keep the same score that we can using 4 pins/LEDs in binary!
Also you're going to find it usefull to know how to manipulate bytes for when you start doing more complex projects.
*/

int ledPins[] = {2,3,4,5}; //Lets just put all our LED pins in an array for easy handling

int inputPin = 12;  // choose the input pin (for a pushbutton)
//the next four variables are four debouncing the button, you can read all about it here:
// http://www.arduino.cc/en/Tutorial/Debounce
int reading;           // the current reading from the input pin
int previous = LOW;    // the previous reading from the input pin
// the follow variables are long's because the time, measured in miliseconds,
// will quickly become a bigger number than can be stored in an int.
long time = 0;         // the last time the output pin was toggled
long debounce = 200;   // the debounce time, increase if the output flickers

byte data = 0; // We'll use this byte to cast the counter into
byte mask = 1; // We'll use this byte kind of like the i in a standard for loop
int counter = 0; // this will increment each time we push the button
int x = 0; //we'll use this to get our index while iterating through the byte


void setup() {
  for(int i=0;i++;i<4) pinMode(ledPins[i], OUTPUT); // make all the LED pins outputs
  pinMode(inputPin, INPUT);     // declare pushbutton as input
}

void loop(){
  reading = digitalRead(inputPin);  // read input value
  //This next line might look a little funny, but this is just checking if the button is pressed
  //See the debounce tutorial for more info on how/why
  if (reading == LOW && previous == HIGH && millis() - time > debounce) { 
    counter++; //The button was pressed so we increment the counter by 1
    time = millis(); // This is for debounce
  }
  previous = reading; // This is for debounce
  data = byte(counter); //this is where we take the counter holding all the button presses and turn it into a byte
  x = 0; // We'll use this variable to get the current position of the bitmask
  for (mask = 00000001; mask>0; mask <<= 1) { //iterate through bit mask. Read more about how this works here: http://www.arduino.cc/en/Tutorial/BitMask
    if (data & mask){ // if bitwise AND resolves to true
      digitalWrite(ledPins[x],HIGH); //Here x represents the current postion of the bitmask iteration, we use it to turn on the coresponding LED
    }
    else digitalWrite(ledPins[x],LOW); // If bitwise AND resolves to false turn the LED off
    x++;
  }
}
   
14  Using Arduino / LEDs and Multiplexing / Up binary counter with trigger on: September 06, 2013, 12:20:53 pm
Hi there

I was wondering if someone on the forum here could help with this binary counter code i am building to test a plc driver pcb...

What i want to do is have 4 digital outputs (binary ) that when triggered by another separate trigger(push button- to ground ) make the 4 bits output move one step up in binary from 0000> 0001>0010>0011... 1111>0000 in a loop each time the button is pressed  .Two pairs of this
1 trigger and 4 outputs that work seperately
I have found some code on you tube for a up counter that has no trigger to change the binary state .

Help would be appreciated and many thanks
Code:
int pin8 = 8;
int pin9 = 9;
int pin10 = 10;
int pin11 = 11;
int pin12 = 12;
int pin2 = 2;
int pin3 = 3;
 
int bin = 0;
int led = 0;
int r = 1;
 
void setup()
{
  pinMode(pin8, OUTPUT);
  pinMode(pin9, OUTPUT);
  pinMode(pin10, OUTPUT);
  pinMode(pin11, OUTPUT);
  pinMode(pin12, OUTPUT);
  pinMode(pin2, OUTPUT);
  pinMode(pin3, OUTPUT);
}
 
void loop()
{
    if(bin == 127)
    {
      r = 0;
    }
    if(bin == 0)
    {
      r = 1;
    }
   
    if( r == 1 )
    {
      bin += 1;
    }
    else
    {
      bin -= 1;
    }
   
    toLeds(bin);
   
    delay(80);
}
 
void toLeds(int code)
{
    digitalWrite(pin8, code & 1);
    code = code >> 1;
    digitalWrite(pin9, code & 1);
    code = code >> 1;
    digitalWrite(pin10, code & 1);
    code = code >> 1;
    digitalWrite(pin11, code & 1);
    code = code >> 1;
    digitalWrite(pin12, code & 1);
    code = code >> 1;
    digitalWrite(pin2, code & 1);
    code = code >> 1;
    digitalWrite(pin3, code & 1);
}

Hi Ray

Thanks for the tips on the module. It would be great to use it in a way, just a pitty on getting a arduino to simulate the original lcd and buttons.

Any else tinkered with the serial data line betwean the display and " radio "

I will follow up more on that module Ray, thanks
