my classmates and i are making a blind walking cane that detects distances. if the distance is less than a certain value, then the vibration motor will turn on. how do we code this. please advise! thank you in advance 
Code it for what hardware, what sensors? Please post schematics and datasheet links to sensors.
Moin rockartsy1008,
sounds like a really good idea!
If you are already making, what have you done for the start?
What materials do you have and what approach are you following?
We might be able to help, if we know some specific question.
