+# Printer Jam
+
+The arduino side of printer jam, where we listen to OSC messages and instruct our printers to execute the messages. 
+
+## Libraries:
+- [ArduinoOSC](https://github.com/hideakitai/ArduinoOSC);
+- [Adafruit Motor Shield V2](https://adafruit.github.io/Adafruit_Motor_Shield_V2_Library/html/index.html);
+- 
+
+The following OSC messages are implemented:
+
+#### /stopAll
+Stops all the motors and stepper motors from running
+_note: for the stepper motor, release could indicate to keep spinning forever.. let's see!_
+#### /black/feed/f
+Run the feed motor of the black printer forwards
+#### /black/feed/b
+Run the feed motor of the black printer backwards
+#### /black/feed/r
+Stop the feed motor of the black printer
+#### /black/feed/speed
+__immediately__ change the speed of the black printers feed motor.
+#### /black/head/f
+Run the head motor of the black printer forwards
+#### /black/head/b
+Run the head motor of the black printer backwards
+#### /black/head/r
+Stop the head motor of the black printer
+#### /black/head/speed
+__immediately__ change the speed of the black printers head motor.
+#### /stepper/f
+Run the motor of the stepper printer forwards
+#### /stepper/b
+Run the motor of the stepper printer backwards
+#### /stepper/r
+Stop the motor of the stepper printer
+#### /stepper/type
+Set the step type __for the next movement__ to (int):
+- `1` "Single" means single-coil activation
+- `2` "Double" means 2 coils are activated at once (for higher torque)
+- `3` "Interleave" means that it alternates between single and double to get twice the resolution (but of course its half the speed).
+- `4` "Microstepping" is a method where the coils are PWM'd to create smooth motion between steps.
+#### /stepper/steps
+Set the amount of steps being moved __for the next movement__ to X
+#### /stepper/RPM
+RPM = is how many revolutions per minute you want the stepper to turn. (similar to speed but much lower value)
+__immediately__ change the RPM of the stepper motor printer's motor.
