Hello smart engineering people,
I'm a mature student doing my last semester in college.
I need to present the following project: a blind-stick that vibrates and buzzes when it is close to an obstacle. I'm using ULTRASONIC sensor.
Would anyone be kind and give me any hints? I don't know even what the block diagram should look like.
Please help.
Thank you.
Kind regards,
Lenny
