DESCRIPTION:Easy circuit to transmit and receive audio through an LED\n\nWe
  are using the 555 chip to make an oscillator (Osc). Our audio signal chan
 ges the frequency of the Osc.\n\nThis signal drives a transistor with Infr
 ared LED collector load........\n\nWe think any voltage controlled oscilla
 tor circuit will do. We think so\n\nOn the receiver side\, a photodiode co
 nverts this light back to current. Circuit then followed with an I-V conve
 rter (a simple resistor).......\n\nAnd rest is audio..It works\n\nVirtual:
