This device calculates degrees and after that - converts to the graph. information.

And version with dimmer to tune LEDS.

yes.  I' measuring only several positions (0, 45, 90, 135 180). And servo waits while arduino measuring at these times

I'd like to present you my new simple project:

Thanks

Components:

Can I use 7bits com port mode?

Hello!
Old mouses had rs 232 interface. And windows still have drivers for it.
I think its interesting to try using arduino as a real com port mouse (via ft232). Does anybody know how to realise this algoritm?  I can't find something useful..

Thanks.

Thanks Nick! I'll try it

Hello.
I need to connect to each other several arduinos. One is like Master. And other are like slave.
Are there any examples for the adrduino spi (master and slave)?

Thanks.

I understood that vinco timers don't have their pin...

Hello.
Yes, I know, that common is only form-factor.
Vinculum datasheet is not like avr...
There is no usefull information about timers:(
