Hi Rui,
I want little help from you. If you have time then please solve my problem. I am use 3 touch sensor and i want increment and decrement with touch sensor.
Touch 1 – LED On & Off
Touch 2 – Increment LED Brightness
Touch 3 – Decrement LED Brightness
I am done with that but problem is coming when i am decrement brightness and i turn off LED it should 1st glow and after again i am touch then off.

Hello Rushi, unfortunately I can’t debug custom code… I would have to test and build the circuit myself, but due to the amount of requests that I receive per day it’s impossible. I can only help if you have an error following one of my exact code, because I’m already familiar with it.
Thanks for your patience!
