That’s awesome, kurandas!
Rotary phone is even better- how did you wire it up? I’d love to see the final project!
Hi elbico! Thanks for trying the project.
If the Morse is being triggered with each key press, check the audio file names, or alternatively swap your Arduino output pins. That way the key press tone will trigger on each key press, but the Morse will only trigger on a correct passcode.
Thanks for the question. That is awesome that you are trying to build one!
I think there are a few ways to do it. I used an app called Arduino Manager on my iPad to view the current readings and set the alarm thresholds. In my next project I will probably use an app called blynk. Basically I measured the ambient light in the room, measured the laser intensity, then set my threshold to a value in between those. If the current value drops below the set threshold, the alarm trips. An if statement is a great way to do this! I am happy to answer any additional questions you may have!
