Twitter VFD Display

Built a display for Twitter messages using a used VFD cashier display, an Arduino board and Flash.

 

The arduino-side code is very basic:

 

#include

#define rxPin 2

#define txPin 3

 

// set up a new serial port

SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin);

  

void setup() {

// define pin modes for tx, rx, led pins:

pinMode(rxPin, INPUT);

pinMode(txPin, OUTPUT);

 

// set the data rate for the SoftwareSerial port

Serial.begin(4800);

 

mySerial.begin(9600);

 

mySerial.print(0x10,BYTE);

mySerial.print(0x14,BYTE);

mySerial.print(0x0c,BYTE);

 

}

 

void loop() {

if ( Serial.available() > 0 ) mySerial.print(Serial.read(), BYTE);

}
