Midterm notes:

• Follow lab that comes up with it, communications
• Ways to connect the motor:
  • Connect motor to transistor (12 volt part supply)
  • Connect to analog out and do analogWrite you can work with the speed
  • H-Bridge turn on and off, and turns motor backwards
  • You can use the same sensor and give it ranges to do different things with the

Class Noes:

• NO and NC - Normally Open and Normally Closed on relay device

• servocity.com for various servos that do different things according to what you want to create

  • Important question is how fast do I need this thing to move?

    • RPM = Revolution Per Minute

      

      on servocity.com, you can look through and see the power, speed, etc and get them accordingly

• Encoder gives reading, and reports back where it’s reading (used for clocks that points at different directions)

• Transistor: from two pins, it connects to the bigger power supply, can also moderate analog on arduino

• Diode - preventative (inductive)

  • bigger motors really needs that

• Mosfet & transistor are the same

• If you wanted to make a record player, you’d need to purchase a motor and a hub

• Red is 5, yellow is 12 (how to convert use desktop power supply on Youtube)
