My code for ADC button handling, it works, but can it be slimmed down?

1. At least 10 times per second.
2. Yes
3. As responsive as any other device, where user presses key and expects immediate feedback.

1. At least 10 times per second
if right>100

so button has to held for ten seconds till you get a response ?

As responsive as any other device

not in my book, i doubt the thing is working after 300mS

2. Yes

like how regular how often really

[CuriousOne]

No.
I mean keyboard is polled at least 10 times per second.
This is general interactive device control, with direct feedback
like your TV remote.
