Fall Electronics session 2021

Easy circuit to transmit and receive audio through an LED We are using the 555 chip to make an oscillator (Osc). Our audio signal changes the frequency of the Osc. This signal drives a transistor with Infrared LED collector load…….. We think any voltage controlled oscillator circuit will do. We think so On the receiver side, a photodiode converts this light back to current. Circuit then followed with an I-V converter (a simple resistor)……. And rest is audio..It works Virtual: https://events.vtools.ieee.org/m/285740
