A description of the project :
This is a walking blind stick that needs to be constructed using a 40 kHz transducer, both transmitter and a receiver. The main aim of the project is to turn on an LED when the stick is 20cm away from the obstacle. The circuit must generate a 40 kHz pulse that should be transmitted with the help of a transducer and a receiver that should receive this signal and turn on an LED indicating a signal is received.
It is essential to have a circuit diagram and detailed explanation of how these two circuits transmitter and receiver and all the explanation of values and components that are used to build this circuit.
Please comment if u have any ideas with the circuit and what might be the components that should be used.
Regards
