guys.. need some help here.... i have an assignment.. details are below...
I'm planning to make some kind of Multi Function Display that usually used in an expensive cars.. it'll shows:
1. Time and date
2. outside temperature
3. rear distance (i'm thinking about parking aid using ultrasonic..)
number 1 & 2 are done... the main problem is number 3..
problem 1. since the sensor will be located outside the car, it must have some kind of weather-protection (rain, dust, etc)... Do you have any idea?
problem 2. do you have any reference about making the parking aid sensor? because, i've tried to built just a distance meter and it doesnt work.. my method is to measure the time delay between transmitted and received signal..
thanks..
