Can I configure an Arduino Uno as a power source to recharge a USB device while being powered by another external power device? I asked ChatGPT for input and it gave me this code:
#include <USBHost.h> // Include USB host library if needed for specific board/shield
void setup() {
// Initialize USB power if required (for boards with USB Host capability)
#ifdef USB_HOST_ENABLED
USBHost.begin(); // Only needed for USB Host shields or boards with host support
Serial.begin(9600);
Serial.println("USB power enabled.");
#endif
// Enable power to the USB port (depends on board; most Arduinos provide this automatically)
Serial.println("System ready. USB power is being supplied.");
}
void loop() {
// Continuously provide power to the USB port
// No specific commands are needed for simple powering.
// If needed, monitor the USB or other pins.
delay(1000);
}
Does this make any sense?
