hello every one hope all of u are fine i have a project in which i want to send data between two arduino uno boards using led not IR but i dont know how to start can any one lead me to the right way i searched a lot but nothing .....
thank you

using led not IR

You want to use a regular LED to send information? The only difference between that and an IR LED is the frequency that you'd pulse the LED.

What are you using as a receiver? An LED won't work. Even though an LED can detect light hitting it, it is incredibly slow to react, and the amount of current that it generates is very small.

What with the extra circuitry you need on the receiver, and the difficulties that you'll have with ambient light, I have to question your decision to not follow the standard.

If you want to use a non-standard mechanism, why are you expecting someone else to have done the work already?
