LEDs as Touch Sensors

[RodM]

Lots of threads on LEDs in this forum. however, thought I would bring this to everyone's attention. How to use an LED as a light sensor, and hence by touching it, as a touch sensor. Utube also has lots of examples of this idea. Certainly expands the use of a humble, cheap, LED

I can remember someone (Stan I think?) mentioning it here about 5 years ago. It got quite a lot of subsequent coverage from a number of people.

So, old news sorry , but it's nice to be reminded.
