Micro controllers

  1. 1. Microcontrollers Brain To Computer
  2. 2. Think About ! How have your students constructed projects in the past? ! How can projects, designed by students, be more exciting, or come alive? ! Where do STEM tools, coding, micro controllers and robotics fit for math?
  3. 3. Microcontrollers allow !Creation of working prototypes, coding and connecting the physical world to the digital world !Students to break out of the traditional project box and CREATE meaningful and effective constructions !Students to think, design, plan out, create, test, and reflect upon their OWN constructions
  4. 4. Microcontrollers ! There are several companies producing microcontrollers for educational use including ! Arduino ! Micro Bit ! Makey Makey ! Chibi Chip ! *Raspberry Pi (different, more complicated, in fact it is a general purpose computer)
  5. 5. Arduino Board ! A small computer that can be programmed to connect and control various electronic parts. ! Has a number of pins that can be set as either input or output ! INPUT – receiving data from items like switches, buttons and sensors ! OUTPUT – sending data to control items such as motors, lights, and buzzers.
  6. 6. Arduino Board has two main elements: ! Hardware– the brain of the board. ! Software– use to send programs to the brain – called the Integrated Development Environment or IDE. ! There are many companies that have created their own specific IDE’s with their own types of boards.

  8. 8. Makey Makey
  9. 9. *Raspberry Pi
  10. 10. Using Arduino - The Integrated Development Environment- ! Simple interface that runs on a computer running Windows, OSX, or Linux. ! Use the IDE to create a “sketch” – Arduino program – that you then upload to the Arduino board using a PC and USB cable. ! The “sketch” tells the hardware – Arduino Board – what to do.
  11. 11. BreadBoard ! Allows for connections to be made. ! Acts as a construction base for electronics prototyping. ! Breadboard dates back to when electronics projects were created on wooden boards. Nails were hammered and wires were wrapped.
  12. 12. Today Breadboards are made of plastic with predrilled holes called tie points. ! You insert components or wires that are held in place by clips. ! The holes are connected by strips of conducive materials running under the board.
  13. 13. The IDE (Integrated Development Environment) is free to download. ! ! Note – Many boards do not require IDE’s or Breadboards to create and construct. Many companies now make kits allowing users ease of access to coding and ease of connections ! Birdbrain Technology Hummingbird Robotic Kit
  14. 14. Microcontrollers allow you to construct projects that - ! Use Motors to make things turn around. ! Use Servos to allow for 90 degree movement. ! Use LED’s that allows you to include different types of lights. ! Use Sensors that allow a project to utilize temperature, Light, Distance, Sound. ! Use LCD’s to allow you to display messages and data.
