Hello fellow Arduino enthusiasts,
I am currently working on an aid for blind people. For this project I am using a Digispark Pro 16 MHz. However, I believe that even if you only know the more common Arduino boards you can still help me.
I am trying to code in a sequence that starts up once the arduino is powered. Once I power up the Digispark I need it to make an vibration motor vibrate twice to inform the blind person that the device is switched on. It sounds simple, but right now I have no idea how to realize this. Can someone help me out?
Furthermore, I am also looking for ways in which i can make the digispark inform the person once the battery runs empty. I am using an external 9V battety to power it. Does someone know how I can do so?
