[HELP] Custom LED controller for automatic turn and reverse signals

Sounds good. Personally I think you'll be fine with the regular TSOP receiver. I'm pretty sure the IR transmission quality comes from the transmitter. But I could be wrong. Also, the amplifier might be optional. Most sounds chips come with some onboard amp, as a "system on a chip".

But overall it looks like you have the gist of things. I would get a headed aka proto board version of an arduino, with all the interfaces for development. When you really want to stick this thing in youre lego, you'll like assembly a single board with all the components, micro, audio, aux components, and then program it with a probe.

So basically, dont waste your money trying to get something to achieve something it wont. Get a dev board, dev the system, and then make a release build that will fit all your polish needs.

Good thread so far, watching with interest :)

Just a small word of warning with the arduino software (which may not even affect you). It caused issues on my PC when I tried to re-load NXT firmware. Had to uninstall arduino, then it would recognize NXT brick in boot mode.

No NXT, no problem.

Here's the police version, which also includes the police light beacons - this model includes all lights which i want to get functionality for through the Arduino based system.
