Sequence Project

• Project - Build a Microcontrolled Pneumatic System.

• Note: 2002 - This circuit was built with provision for a current limiting resistor which was not installed. "Latching up" of one of the coils occured intermitenly until a small resistor 220 ohm was included. In future build this with a 220 ohm series resistor (installed where the current limiting provision goes)to prevent this. Also switch to IRL520 mosfet (L indicates more D to S current for specific Vgs)
• sequence
  • complete with led's then hook up to hardwqare after your instructor has checked.
  • must breadboard 2N7000 circuit
• What to hand in
  • Complete a
    • flowchart
    • basic program
  • assemble, download into a pic and troubleshoot using LEDs for output.
  • hook up to hardware and demonstrate use
  • Complete
    • an electrical schematic using this template from multisim
      • circuit sketch - note add two 220 ohm resistors as per note above

• a pneumatic schematic using this vectorworks template
  • circuit sketch
