This DIY driving assistant helps with parking and blindspot monitoring

Relating to driving a automobile, one should at all times be on alert for doable obstacles and different drivers within the subsequent lane over for altering lanes. However as a result of older autos that lack built-in blind spot detection or parking sensors would require fairly dear upgrades, Redditor cisco_s_spedgang determined to make a DIY distance sensing system for much cheaper.

The thought was to take a complete of six HC-SR04 ultrasonic sensors and place them round a car, with two on both aspect, one on the entrance, and one on the again. From right here, the linked Arduino Uno will get the gap measurements and performs a number of checks primarily based on the ensuing values in addition to present a corresponding purple LED for when the automobile will get too near one thing else. Upon hitting the flip indicator inventory for signaling a lane change, the blind spot help system will see if there may be one other car on the identical aspect because the flip sign and sound a loud alarm if it’s unsafe to cross over.

In its present type, this Arduino-based setup depends on a collection of wires that span the whole size of the automobile, though cisco_s_spedgang does plan on tidying issues up sooner or later. To see extra about how this mission works, you’ll be able to learn its publish right here on Reddit.
