Help with Photoresitor sensor

Hello all,

I have purchased the BOE BS2 and a bunch of sensors. I have been able to work without a problem with the PING[noparse]:)[/noparse] and IR sensor and now I want to get the Photoresistor to work so I can do light detection.

The Photoresistor sensor came from Parallax without documentation and on the product link (http://www.parallax.com/detail.asp?product_id=350-00009) there is no documentation either (unlike almost every other product).

I have looked in the support area, the Downloads/Tutorial areas on the site but I can't find any information. Does anybody have any documentation on how to use and program (i.e. code sample) this sensor?

Thanks!
Ethan

    Chapter 6 of the Robotics tutorial in the Stamps in Class series covers photoresistors and the BS2.

    Ethan,

    Remember, certain components such as resistors (which the CdS photocell is) and capacitors won’t have documentation written by us; however they will almost always be included in projects in one of our books. Take care.

    Thank you. I realize Parallax would not be providing docs but was hoping to get at least some basic wiring (where on earth to plug it in...) and a list (if any is required ) of capacitors, resitors or converters if -- of course-- I need any of them.
    Don't need professional docs, just a tip of how to get started or advise from someone who has done it before.

    Thanks!

    May I·suggest downloading "What's a Microcontroller?" and "Robotics with the Boe-Bot" for reference? ·Both of these beginner's tutorials show schematics and wiring diagrams for the basic components in their accompanying kits, including the photresistor.

    In WAM, photoresistors are introduced in Chapter 7.

    In Robotics, photoresistors are used in Chapter 6.

    You will find lots of sensor circuit examples throughout the other Stamps in Class texts as well, and all are free to download. For more fun and games see the Stamps in Class mini-projects thread:
