Unit 08 - Analog Read with Arduino

  1. What the Heck is Ohm's Law?
    1. Goto the pHET Circuit Construction Kit
    2. Work through these activities:
      1. Ohm's Law 1
      2. Ohm's Law 2
  2. Analog Read Arduino
    1. Work through: Analog Read and the Potentiometers
    2. Work through: Analog Read and Photoresistors


A-8.1

I can wire a potentiometer to my Arduino

A-8.2

I can program my Arduino to read the position of the potentiometer

A-8.3

I can set the potentiometer and then explain how the reading will change if the positive and negative wires are reversed.

A-8.4

I can wire a photoresistor as an analog input

A-8.5

I can program my Arduino to read the relative brightness on my photoresistor

B-8.6

I can use “map” to adjust my photoresistor readings to change the range of numbers it will report
