→‎Analog Input

val = analogRead(potPin); // read the value from the sensor

</code>

* Q: Looking at the Arduino help for that function (<code>analogRead()</code>), what do you think the value <code>val</code> will be for those highest and lowest voltages in the previous questionat V_IN?* Q: How can you verify your ideaguess? (... I have two ideas ... )

=== other loads ===

* photoresistor from your 147A kit... 160k - ~10k (depending on your lighting conditions).
