There is a new technology that newer cars are equipped with. It's called autonomous emergency braking; no matter how serious we are while driving, we do get distractions, such as Facebook or WhatsApp notifications, which tempt us to look away from the road onto the screen of our phones. This can be a leading cause of road accidents; hence, car manufacturers are using autonomous braking technology. This generally relies on long range and short range radars and it detects the proximity of other objects around the car, and in the case of an eminent collision, it applies the brakes to the car autonomously preventing them from colliding from other cars or pedestrians. This is a really cool technology, but what's interesting is that we would be making it today with our own bare hands.

To make this, we will be using the IR proximity sensor to sense the proximity of objects around it. Now go ahead, grab a double-sided tape, and attach the IR distance sensor at the front...
