for an installation i need the ramp function and arduino-audtio-tools sd-a2dp-player in one sketch. if i do so, with player active, no ramp anymore possible. i need a slow ramp up over 5sec or more when the player starts, slow down when the player stops . something interferes there. how could i get to the core of the problem? where to look? i am not a real programmer...but experimentalist

hello, i use the rbd lib to slowly ramp up and down the motor in an art installation..that all works very well...the motor start to spin for a time on a button pressed and then slows and stops.. the installation has sound as well. the sound shall also fade (ramp) in and out but faster than the motor. could i use and instance of this lib also for send a number to an external device, not pwm, to set its volume?

I'm using an H-bridge motor controller that has only 2 input pins: in1 is a PWM-capable Enable pin, and in2 is a High/Low Direction pin. How should I define the Motor Constructor so that forward() sets HIGH on the pin going to in2, and reverse() sets LOW on that same pin? (I don't have two separate direction pins on my controller)

Currently I'm just using motor.on() and manually setting the direction pin before I turn it on like the code below, but I was hoping there might be a way to better utilize the library.

RBD::Motor motor(6); // pwm pin
const int DCdirection = 7;

void setup() {
motor.rampUp(3000);
}

void loop() {
motor.update();

if(DCdirection == HIGH){
DCdirection = LOW;
}
else{
DCdirection = HIGH;
}

if(motor.onTargetSpeed()) {
if(motor.isOn()) {
motor.rampDown(300);
}
else {
motor.rampUp(300);
}
}
}

Thanks for creating and sharing your suite of libraries.

Is it possible to use this library to control an H-bridge that only has two pins? So instead of a PWM pin, and forward + reverse pins, only have two PWM pins. For example, if you wanted to move the motor forward, you would set the forward PWM pin to a non-zero value, and the reverse PWM pin to 0.
