Nyan Cat on a floppy drive [IMPROVED]
7Nyan Cat on a floppy drive. Powered by an Arduino Mega running Moppy by SammyIAm.
Fixed the crappy audio in Moppy. Oscillating the drive head sounds WAY better than running it all the way from end-to-end. This also means you do not need to call resetAll() when you init the drives, and it also means no more interruptions in longer notes from the head changing directions. If you're interested, here's my patch to Moppy:
void togglePin(byte pin, byte direction_pin) {
//Set the current direction
digitalWrite(direction_pin,currentState[direction_pin-FIRST_PIN]);
//Pulse the control pin
digitalWrite(pin,currentState[pin-FIRST_PIN]);
//Configure next pulse
currentState[direction_pin] = currentState[direction_pin] ^ currentState[pin];
currentState[pin] = ~currentState[pin];
}
