Re: InfraRed ramblings

Thanks Mark!

I was considering laying a limit switch flat along the outer edge of the disk, and use a notch to catch the limit switch roller. But I'm liking the hall sensor even more:

Re: InfraRed ramblings

You can also use a hall effect IC and a small magnet. The hall effect ic's come in a 3 pin TO-92 package and are easy to interface to your micro.

For example

led modulation unnecessary too.

if the distance between led and...
