Hi.
I currently involved in a project of navigation for my rover. I use arduino uno as microcontroller. If u all already seen a video, Self following luggage by Ben Heck Show. I managed to get the receiver code but i try to convert it from serial motor driver to AF_Motor.
The video said, distance is not they wanted. The receiver will only determine which motor to move as it receive ping from transmitter build using the same HC-SR04 ultrasonic sensor. The idea is there will be 1 transmitter module and 1 receiver module with 2 sensors. All the respective transducer from sensors have been removed according to its own functionalities.
My big problem is, is there any indicator that will represent receiver transducer have receive ping from transmitter transducer other than echo duration ? I just want to display something when the receiver receive ultrasonic sound from transmitter. So it will determine whether receiver receive something of being passive waiting for echo. Thats all. With or without NewPing lib i wouldnt mind. Please help me
Thanks
