I need help on my project here.here's how the project goes:
A blind man walking in a supermarket.Then he will be guided by a transmitter receiver to where he want to go.example he is looking for apple.the device will guide him such as "walk left....now turn right....walk straight". something like this.from what i know there must be a transmitter and receiver.but i don't know what kind and the freq and stuff.
So please help me on how to build the devices and what are needed and stuff.Thank you very much!
