Just build my first project on arduino, seems to work fine, decided to change wiring, I used 2 interrupt pins with push buttons and pull up resistor + bouncing, 4 analog pins 3 output 1 input, 2 pwm pins output
Soldered one button to interrupt pin to test - and noticed that I get weird results on same code that worked fine, thought it was bad soldering - then discovered that its my fingers that make this interference just by touching arduino board
How to deal with this?
Update
Removed floating pins, works fine
