Unit #2-08

Learning Outcome

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

• combine different controllers together, again

Review

• resistors

• servo

Lesson

• a potentiometer is a variable resistor

  • yours is a 1 MΩ

    • meaning it could be 0 Ω to  1 MΩ

  • here is how you could use it in a circuit

• this might help to read the value of a resistor

  • remember, you have 4.7 KΩ resistors

Activity

• nil

Daily Assignment

• create project with a potentiometer and a servo

  • when the  potentiometer is reading 0 Ω, the servo is at 0°

  • when the  potentiometer is reading 1 MΩ, the servo is at 180°

• only use code we have used so far

  • no using a "map" function!

Extra

• if you finish early, write the above program on your CircuitPython board
