| Receives from the hardware serial, sends to software serial. | |
| Receives from software serial, sends to hardware serial. | |
| The circuit: | |
| * RX is digital pin 10 (connect to TX of other device) | |
| * TX is digital pin 11 (connect to RX of other device) | |
| Note: | |
| Not all pins on the Mega and Mega 2560 support change interrupts, | |
| so only the following can be used for RX: | |
| 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69 | |
| Not all pins on the Leonardo and Micro support change interrupts, | |
| so only the following can be used for RX: | |
| 8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI). | |
| created back in the mists of time | |
