to sample the Pulse Sensor with consistent and regular timing. The code is setup to read Pulse Sensor signal at 500Hz (every 2mS). The reasoning for this can be found ...

Once we power the bomb, we are asked to set the password and the time we want to give it. Once the password and timer have been set, the bomb will be activated. The time is reduced by 1 second. If the ...
