Arduino Tutorial 08 - Switch-Case and While

The eighth in a series of introductory Arduino tutorial videos.
If you have any questions or comments, please post below.

This video explains and demonstrates the "switch / case", "while" and "do, while". A photocell is also introduced.

A breakdown of the example code is provided, explaining the purpose of each line and component.

The memory location of lightVal?

You seem to be calling it as a int inside the while which could be setting it as new rather than replace. Try it without the int inside the while

Nice Ryan. Good work. 

I am working on a project based on 2 sensors which work with one LED (one will turn it On and another one will turn it off, for 3000 times (without timers)). Dont know how to use switch-case for that outcome. 

Please help.

Hi Ryan
What if i want to use a button to shift between 5 different cases and the cases should loop until the button i pressed again?

Like first case is the AnalogInOutSerial, case 2 is Fade example and so on?
I want the fade example to loop until the button is pressed and then it goes on to the next program. :)

Hi just wondering what the fix was for the While loop problem was as i have similar problem and i just can't figure it out

[Elstarda]

So would be

lightVal = analogRead(lightPin);
