What I Did

• For this assignment I focused on using the syringe as a linear actuator with timing based code
  • I also experienced with other materials and in general got comfortable with the board and experimenting with pressure

Linear Actuator with a Syringe

• After testing that the syringe was working using the red and blue buttons manually I uploaded the lesson timing example to test with the syringe. This example in the loop function is for switching on the pumps and blow function if the red button is pressed.

  void loop() {
    if (readBtn(RED)) {
      switchOnPump(2);
      blow(); // setValve(2, OPEN); setValve(1, CLOSED); setValve(3, CLOSED);
      delayWhileReadingPressure(1000);
  
      switchOffPumps();
      vent();
      delayWhileReadingPressure(1000);
    }
    else {
      delayWhileReadingPressure(100);
    }
  }

Hardware

In class we received the hardware for Programmable Air. This diagram was a helpful reference for what is on the board.
