My group searched on how to make capacitive touch circuit since capacitive sensor IC is not available here in the Philippines. We came up to this site, how to make touch circuit using NE555. But when we've tried to implement this on our thesis it didn't work for multiple inputs. Do you know how to make a capacitive touch sensors that outputs one signal (when you pressed it turns on, and when not its off). Please help us. Watch this video at to have an idea on our project. Thank you.
