1  Using Arduino / Project Guidance / Re: Voltage on pin12. on: September 06, 2011, 11:23:56 am
Are the voltages on the PWM pins (13,12) at 5 volts on the Arduino Mega 2560?

I have an Arduino Mega 2560 is the voltage on the this pin 12 I perform the following:

void setup() {               
  // initialize the digital pin as an output.
  // Pin 13 has an LED connected on most Arduino boards:
  pinMode(12, OUTPUT);     
}

void loop() {
  digitalWrite(12, HIGH);   // set the LED on
  delay(1000);              // wait for a second
  digitalWrite(12, LOW);    // set the LED off
  delay(1000);              // wait for a second
}

Regards.

3  Using Arduino / Sensors / I would like to use an Arduino Mega for data aquisition on: June 11, 2011, 08:44:55 pm
I would like to use an arduino mega for data acquistion.
I have seen some projects where the data is stored on FAT disk I would
rather retrieve the data through the USB cable.
can someone suggest a shield for that?

4  Using Arduino / Displays / Suggestion for LEDs for the PWM outputs. on: June 08, 2011, 07:47:02 pm
Could someone suggest an LED from digikey to use in the LED example?
Or would the following
http://media.digikey.com/pdf/Data%20Sheets/Lite-On%20PDFs/LTL-307EE.pdf
be an acceptable LED for PWM outputs.
