I want to build a circuit with the push buttens supplied by parallax and can't find a schematic of how to connect one. I know it take two switches to do. Can anyone help me, an already existing schematic from anything would be fine. would be fine.
Take a look at parallax professional development board p/n 32111 schematic.
I found it thanks
Just an FYI in case you have a need.
There are many debounce solutions but this is one of my favorites:
They also make debounce circuits. The MC14490 is one such example. Also Maxim makes several varieties, they used to send their samples to practically anyone, but that changed a while back and I found fault with their logic, but did not complain. You might be able to find those parts via DIgi-Key as it happens.
