Smart Blind Stick using Arduino Circuit Diagram. The below circuit diagram shows the complete hardware wiring setup of the Arduino-based Smart Walking Stick for the Blind people, detailing how the ...

Step 4: Assembling The Circuit. We will need to design two circuits for this project. The first circuit will be placed at a suitable place in a blind man’s stick and the second one will be an RF ...

The complete circuit diagram for Smart Blind Stick is shown below. It is pretty simple as we only need to connect three ultrasonic sensors and one JQ6500 voice module. The complete board is powered by ...

Assemble the circuit as per the diagram. Upload the code to the Arduino Nano using the Arduino IDE. Power the system using a 9V battery or a rechargeable Li-ion battery. Test the stick by placing ...

Blind Stick Circuit and Working. Fig. 2 shows the circuit diagram of the stick for the blind. It is built around an IR sensor module connected across CON2, a PNP transistor BC558 (T1), a buzzer (PZ1), ...

Mount the three ultrasonic sensors at the front of the stick, each angled 60 degrees apart to cover a wide detection area. Connect the sensors to the Arduino as per the schematic diagram. Attach the ...
