If the interrupt is triggered randomly without you even touching the switch, that means some noise is definitely causing the issue. If you have an oscilloscope you can hook it up to D2 to see what is happening. Try adding a 100uF and a 0.1uF cap on the 5V before it connects to the Arduino circuit. | |

| Dec 27, 2015 at 22:38 | comment | added | Alex | Why would a pull-down system have more noise immunity than a pull-up system? | |
| Dec 27, 2015 at 13:58 | comment | added | Gerben | You could try; lowering the pull-up resistor. Moving the button away from the boost converter and it's wires. Move the pull-up nearer to pin 2. Use a pull-down system (by swapping R1 and SW1), instead of pull-up. PS the capacitor isn't used for decoupling here, but as a low-pass-filter. | |
