Maestro maestro(PTC4,PTC3);

int main()
{
    maestro.setBaudRate(9600);

    // limit speed for each servo
    for (uint8_t i = 0; i < 17; i++) {
        maestro.setSpeed(i, 10);
    }

    while (true) {
       // set servo on channel 0 to 90 degrees
       maestro.setServoAngle(0, 90);
       wait(2);

        // set servo on channel 0 to 45 degrees
       maestro.setServoAngle(0, 45);
