We have a new project. It's a obstacle detector that uses ultrasonic sensor/s with the proper circuitry mounted on a toy car. The project should respond like this. Once it senses an obstacle, it would either turn left or right so that it would not hit the obstacle. Our professor noted that if we can make the toy car move backwards first before turning left or right, she would give a credit for that. I have already googled for this project and I found this link.
I just don't know if these circuits are correct for the transmitter and receiver. However, the transmitter is being drove by a 555 timer operated in the astable mode. I think I can do that one since I can always refer to the datasheet of NE555. For the receiver, I honestly can't understand how the circuit works.
Am I also to use Hbridge for the steer?
I would appreciate any useful information you can give.
