Hello, this is my first post and my first original idea for a project involving Arduino.
First of all, I'm really new at all of this and the extent of my knowledge in electronics is basically V = IR.
Basically, what I'm trying to do, is to modify an unknown board that controls a flashlight. It has a tactile button that I want to replace with a capacitive touch sensor using the metal button as the contact point. The voltage going through the tactile button is reading over 5v so I planned on controlling a relay with an attiny45 to complete the circuit when the sensor is touched.
Is there anything crucial that I'm not considering? Or is there an easier way to achieve the same goal without needing a microcontroller?
Thanks for any help you can offer,
