continuous_send.ino

/*
 This sketch continiously sends characters over serial port. It begins with character of code 0x20 and sends up to code 0x40.
 There is 0.1 second delay between each character sent which you can change.
 The number of characters sent is displayed on first and second line of LCD.
 The characters sent by Arduino MCU over the USB cable reaches Arduino IDE and it can display it through its Serial Moniotor software.
 Invoke Serial Monitor by pressing Ctrl + Shift + M together.
 Change limit 0x40 to higher value to see more codes sent to printer.
 
 The circuit:
 * LCD RS pin to digital pin 12
 * LCD Enable pin to digital pin 11
 * LCD D4 pin to digital pin 5
 * LCD D5 pin to digital pin 4
 * LCD D6 pin to digital pin 3
 * LCD D7 pin to digital pin 2
 * 10K resistor:
 * ends to +5V and ground
 * wiper to LCD VO pin (pin 3)
