Trang 17Results of our system
• By 2 quick tests, we will determine sensor works correctly or not?
• Test 1: Car runs encountered fixed obstacles on the road
• Test 2: Car runs encountered moving fast obstacles on the road
• Through two tests, we can see that the sensor operate quite accurately Testing showed that cars are separated over 10
cm from obstacles
• We sent you testing clip by dropbox.
Trang 18• After finished our project , we got more knowledge about Safety Parking Car system and microprocessor AVR, how to control motor using PWM, module LM298 and, Ultrasonnic Distance Sensor HC SR04 ; and many peripheral interface , and have the chances to practice what we learn in lectures… This is very useful experience for us to work well in the future
