Thanks, you are right. But I'm not sure where it should be placed, and why??

You are correctly doing little in the ISR: set a flag telling the main program to handle something. You should unset that flag when you are done doing handling the something you needed to handle. Guessing from your code: in the alarm() function.

It seems as if the interrupt on pin 2 is not triggering the function. Not sure what is wrong.

I did make the change in the alarm function, but still not getting the interrupt to trigger. } trigsensor = false; readKeypad(); }

What does the signal on the interrupt pin look like? You initialize it to trigger on a rising edge -- is that what is happening with the actual signal?

like so
```
add language identifier to highlight code
```python
def function(foo):
print(foo)
```
put returns between paragraphs
for linebreak add 2 spaces at end
_italic_ or **bold**
indent code by 4 spaces
backtick escapes `like _so_`
