Observing problems and trying to find a solution for it is one step towards creating a genius.
Let’s explore a common problem which we face while driving on hills particularly at hairpin curves and blind corners when the driver is sceptical if a vehicle is arriving from the other end of the corner.
Ever thought of how safer it would be by knowing if there is another vehicle coming from the other side of a blind corner.
Things you need
Power – 2
IR – 2
LED – 2
Buzzer – 2
Led cables – 2
Power banks – 2
USB cables – 2
This project is created in two sections:
- First we create the circuit using Havi Elements.
- Second, we create a blind turn scenario using our crafting skills.
Section 1: Creating the circuit.
IR (Infrared) sensors are used to detect the presence of the object. Checkout How IR works for more details.
Coupling IR sensor with Buzzer and LED will make the buzzer emit sound and LED glow whenever an object is detected by the IR Sensor.
Snap the elements to prepare the circuit as show here.
Section 2: Creating a blind corner scenario.
A hairpin bend or blind corner is a turn on the road where the view of what is behind the corner is obstructed either by buildings, hills or trees. Warning signs are often placed on such roads to warn traffic.
How it works?
The IR sensors are placed on the left lane of either sides of the curve.
As car approaches the curve, it is detected by the sensors placed their and a notification LED glows on the other side of the curve with a buzzer sound to alert the traffic coming form that side about the approaching car.
This works on both the sides of the curve.
This notifies the driver about the vehicles approaching from the other side of the blind corner. The driver then can carefully take the turn and ensure a pleasant and safe journey.
Advantages when implemented in the real world
Accidents can be prevented and a lot of lives and loss of vehicles can be saved when implemented at hairpin curves in the real world.

what will happen when a car gets break down what will the sensor do does it conti
nously make a noise?

First of all, Thank you so much Preetha for the wonderful insights on it.
Yes, it may happen that someone breaks down and the buzzer keeps hitting the opposite side.
Apparently, opposite siders will know that someone is there. Plus, the one who breaks down will realize that he/she should not break down as it keeps buzzing.
