user4594: I have an Arduino Uno. I am building a custom shield and was wondering how I would connect two of the LEDs on the shield to the TX / RX LEDs on the Uno. Digital pins 0 and 1 seem obvious, but after further research, it appears that they are not for this.
In better terms, I want two LEDs on my shield that replicate the TX / Rx LEDs on the Arduino Uno.
How would I do this?

user3825: If you need just indicate data on TX/RX you can make simple circuit on shield bound to TX/RX lines.


user368: The TX/RX LEDs on the Uno are not connected to the main MCU but are instead connected to the USB communication chip, be it a FTDI or ATmega16U2. You would need to solder wires to the appropriate connections on the board and then connect them to the shield in question.
