  Abstract: Using a clear flexible PVC tube filled with mineral oil as an optical fiber, a laser diode is submerged in one tube side with a photo-resistor in the other side. A transmitter and a receiver Arduino are connected to the laser and resistor respectively. A message typed into a laptop is passed to the transmitter Arduino that converts a text message into binary ASCII, one character at a time. It transmits each character as a packet with a leading sync pulse to align timing for the transmitter and the receiver. Each received packet is converted back to a character by the receiver Arduino and then displayed on a connected laptop.
