Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

So the TX and RX leds are driven by a couple of pins on the ATmega32U4 (see a comment on the hardware connection below) to make it look like they are on the serial bus. They were not intended to be ...
