| SerialPassthrough sketch | |
| Some boards, like the Arduino 101, the MKR1000, Zero, or the Micro, have one | |
| hardware serial port attached to Digital pins 0-1, and a separate USB serial | |
| port attached to the IDE Serial Monitor. This means that the "serial | |
| passthrough" which is possible with the Arduino UNO (commonly used to interact | |
| with devices/shields that require configuration via serial AT commands) will | |
| not work by default. | |
| This sketch allows you to emulate the serial passthrough behaviour. Any text | |
| you type in the IDE Serial monitor will be written out to the serial port on | |
| Digital pins 0 and 1, and vice-versa. | |
| On the 101, MKR1000, Zero, and Micro, "Serial" refers to the USB Serial port | |
| attached to the Serial Monitor, and "Serial1" refers to the hardware serial | |
| port attached to pins 0 and 1. This sketch will emulate Serial passthrough | |
| using those two Serial ports on the boards mentioned above, but you can change | |
| these names to connect any two serial ports on a board that has multiple ports. | |
