Introduction: Ultrasonic Sensor Buzzer for Blind
I have made a ultrasonic sensor with buzzer for blind, This ultrasonic sensor detects the the object and the buzzer makes a kind of sound which can help blind people that there is an object in front of them.
- Ultrasonic sensor(ping)
- Resistor 100(ohms)
- Piezo Buzzer
Step 1: Circuit Diagram
- I have used 3 pin ultrasonic sensor(ping), I have connected GND to ardiuno GND, 5v to arduino 5v and sig to arduino 8 pin.
- I have used piezo buzzer for the indication of sound and added resistor to control the current.
Step 2: Progamming
In this code I have written both code combined as you can see in the picture attached, first I have written ultrasonic sensor and buzzer in void setup and void loop.
