Description |
Arduino Due |
Arduino Due is the CPU used to execute the main code of both the transmitter and receiver |
Photodiode |
The photodiode is the device responsible for the acquisition of the light and the conversion of it into a current which can be used to extract the information associated to it
|
LED (Light Emitting Diode) |
The LED is used to convert the digital data outputted by the Arduino into visible light which is in turn captured by the photodiode on the receiving end
|
Operational Amplifier  |
The Operational Amplifier (OpAmp) is responsible for the conversion of the current generated by the photodiode into a voltage whi can be easily read by the receiving Arduino |
Integrated Hex Inverters 74HC04  |
These logical inverters are used to provide a better shaped input signal to Arduino, this way the signal is more immune to the noise in a neighbourhood of the logical threshold corresponding to the reading of the Arduino |
