The Onkyo TX NR646 may shut off at high volume due to a built-in protection mechanism designed to prevent damage to the receiver and connected speakers. When the volume is pushed to high levels, the receiver may overheat or draw too much power, triggering the protection circuit to shut off the unit. This is a safety feature to prevent damage and ensure the longevity of the receiver. It is important to use caution and not exceed the recommended volume levels to avoid triggering the shut-off mechanism. **

You can connect two Arduinos to each other using pins 0 and 1 (TX and RX) by establishing a serial communication link between them. You will need to connect the TX pin of one Arduino to the RX pin of the other Arduino, and vice versa. Additionally, you will need to connect the ground (GND) pins of both Arduinos together to complete the circuit. Once the physical connections are made, you can use the Serial library in the Arduino IDE to send and receive data between the two Arduinos. Keep in mind that you may need to disconnect the TX and RX pins when uploading new code to the Arduinos, as these pins are also used for programming. **

One can use Remote Desktop to access a computer from anywhere in the world as long as there is an internet connection.
