Contrôler un servo
This section gives tips for how additional electronics can be connected to the Romi 32U4 Control Board.
Free I/O pins
If you want your additional devices to send or receive information from the AVR, you will need to connect them to one or more of the AVR’s I/O pins. The pin assignment table in Section lists all of these pins and how they are used. Many of the I/O pins are already being used for some other purpose on the board, but there are 8 free I/O pins: 0, 1, 5, 12, A0, A2, A3, and A4. Any of the free I/O lines can be used as basic digital inputs or outputs; each pin also has some special capabilities.
Pin 0 (PD2) and pin 1 (PD3) are the RX and TX lines of the AVR’s TTL serial port.
Pin 5 (PC6) is a hardware PWM output and is usable with the Arduino analogWrite() function. Pin 12 (A11/PD6) can also be used as a PWM output, but it is not supported by analogWrite(), and using pin 12 for PWM might conflict with uses of pin 6 (which controls the buzzer by default) as these two pins are complementary outputs of Timer4 channel D.
Pins 12 (A11/PD6), A0 (18/PF7), A2 (20/PF5), A3 (21/PF4), and A4 (22/PF1) can be used as analog inputs.
