Unit #5-08

Learning Outcome

At the end of this lesson, you will be able to:

• control a 28BYJ-48 DC 5V stepper motor

Review

• review Robot:Bit extension

  • inside this extension is "robotbit.StepperDegree(robotbit.Steppers.M1, 0)" code

Lesson

• there are 2 connections for these types of "continuous" turning stepper motors

  • M1 & M2
    robotbit.StepperTurn(robotbit.Steppers.M1, robotbit.Turns.T1B0)
    robotbit.StpCarMove(10, 48) 

Activity

• plug the stepper motors on the Robot:Bit

  • note the colors of the wires and the terminals, make sure they match!

  • note the number you placed the wires on (ex: M1 or M2)

Daily Assignment

• click on provided link to create a new GitHub repo

  • call the repo: TEJ2O.1 ⇢ Unit5-08

• create a program that moves the stepper motor back and forth

  • if need be join another student

  • create a program that has 2 - 28BYJ-48 DC 5V stepper motor and a distance sensor

  • assume that the motors are driving 2 wheels

  • make the wheels move forward

    • if there is an object within 10 cm of the distance sensor, the motors stop, the card reverses 10 cm, it then turns 90° and then continues moving forward

Extra

• do the same assignment, but in Python

  • not sure how to do this!
