Using Arduino to Generate CV Gates (5V Pulses)

I'm relatively new to Arduino. I'm trying to build a gate sequencer to use with an analog synth. I need to be able to send 4 separate 5V pulses. Does anyone have any tips for getting started.

Does anyone have any tips for getting started.

Spend a day ofr two in the tutorial section - http://arduino.cc/hu/Tutorial/HomePage -
especially the digitalWrite() , the Serial class and the analogRead().

By working through the examples you will learn a lot about how to do this, what the arduino can do and what it cannot.
I expect you have a first sketch working at the end of the first evening maybe even faster!

Assuming you don't need much current to drive those pulses high, maybe this will give you some ideas

byte pin2 = 2; // connect to D2
byte pin3 = 3; // D2
byte pin4 = 4; // D4
byte pin5 = 5; //D5
byte pulseWidth = 10;  // width in mS

void setup(){
pinMode (pin2, OUTPUT); // set pin as an output
digitalWrite (pin2, LOW); // set pin as low output to start
pinMode (pin3, OUTPUT);
digitalWrite (pin3, LOW);
pinMode (pin4, OUTPUT);
digitalWrite (pin4, LOW);
pinMode (pin5, OUTPUT);
digitalWrite (pin5, LOW);
} // end void setup

// repeat loop over & over
void loop(){
digitalWrite (pin2, HIGH); // pulse the pin High
delay (pulseWidth);          // for this long
digitalWrite (pin2, LOW);  // and then back low
delay (1000);                     // wait this long and then do the next pulse
digitalWrite (pin3, HIGH);
delay (pulseWidth);
digitalWrite (pin3, LOW);
delay (1000);
digitalWrite (pin4, HIGH);
delay (pulseWidth);
digitalWrite (pin4, LOW);
delay (1000);
digitalWrite (pin5, HIGH);
delay (pulseWidth);
digitalWrite (pin6, LOW);
delay (1000);
} // end void loop

CV GATE signal can be read by older synth?
