First Arduino Project Photoresistors Piezo Speaker Flash

This is a mixture of the tutorials that I found on arduino.cc that uses two photocells to measure light at two spots on a breadboard and creates a tone through a piezo speaker that has a varying pitch and beat according to the incoming light values.

can you please comment on the driver circuitry on the piezo speaker? they operate at high voltages and can not be driven with a typical audio amp. they take d type and ab type supposedly ..............................­................ thx

@lotec11 Hey this is a super old project at this point so I don't remember the details, but I wasn't using any sort of high powered anything in the video, just a very small piezo speaker. The tutorials I mashed up here were straight off the arduino.cc site, the piezo one is here (won't let me add the link, putting it in the description) I just mixed that with one on reading photo sensors.

@lucirz This was a while back now but I believe I was using TinkerProxy to pass along the data from the arduino to flash, so the data path goes like this: Arduino read physical resistance from photoresistor (comes in through analog port on arduino so I get a value 0-1024) use Serial.print(analogRead) to write out the data to the serial port, use TinkerProxy to pick it up off the serial port on the PC and pass to something that can be read using Socket in AS3, hope it helps let me know if not

so this is using adobe flash? how?

Hey sorry I take so long to respond I have a hard time focusing :), n e way check out tinkerproxy it's great for arduino->flash I added links to the more info on the video, also check out my other videos the bot is the most impressive thing I think I did with the arduino but it's now on the floor in my car dead to the world :(. Also been toying with porting touchlib to flash it's been working okay (no threading damn't).

@wafflejock how did you get the levels of the photoresistors to appear on screen?

i had a hard time understanding how to get output into flash.... can u maybe help me out a bit???

You should definitely make a tutorial on this.

That would make you god in my world.

very cool
