Arduino serial device

[webvrnsfw]

Added a simple serial device that can interface with an Arduino for DIY sex toys. The device accepts SingleMotorVibrate commands. Not sure if this is worthy of a merge, or how much more effort it would take to make it worthy, so consider this a proposal for discussion. The corresponding Arduino code (in my case) looks something like this:

// pin for enabling the DC motor controller
const int enablePin = 12;
// pin for providing a PWM signal to the motor controller
const int motorPin = 14;

const int min_speed = 100;
const int max_speed = 1000;

const int cmd_ack = 0x01;
const int cmd_enable = 0x02;
const int cmd_disable = 0x03;
const int cmd_speed = 0x04;

void setup() {
  Serial.begin(115200);
  pinMode(motorPin, OUTPUT);
  pinMode(enablePin, OUTPUT);
  digitalWrite(enablePin, LOW);
}

void loop() {
  if (Serial.available() > 0) {
    int incomingByte = Serial.read();
    switch(incomingByte){
      case cmd_ack:
        Serial.write(cmd_ack);
        Serial.flush();
        break;
      case cmd_enable:
        digitalWrite(enablePin, HIGH);
        break;
      case cmd_disable:
        digitalWrite(enablePin, LOW);
        break;
      case cmd_speed:
        while(Serial.available() == 0) {
          delay(1);
        }
        int speed = Serial.read();
        if (speed == 0) {
          analogWrite(motorPin, 0);
        }
        else {
          int val = (speed / 255.0) * (max_speed - min_speed) + min_speed;
          analogWrite(motorPin, val);
        }
        break;
    }
  }
}

It's taken almost a year, but we're close to having this be possible. I'm working on abstracted protocols now in #453 and #559, after which I'll be working with people building hardware to discuss a simple format for a generic-message-only (vibrate/rotate/linear) hardware protocol.

And 3 years later, this is actually doable via our websocket device system that I just finished documenting in our dev docs (see the Inflating buttplug portion of the dev guide at https://docs.buttplug.io) . Closing this.
