Obstacle avoiding car without arduino ! How to make obstacle detection car project using ir sensor

#schoolproject #pathfinder #selfdrivecars #arduinoproject
This obstacle-avoiding car uses an IR sensor to detect objects in its path. When the sensor detects an obstacle, its output signal changes state. This signal is connected to a relay module, which acts as an electronic switch for one of the two BO motors. Upon detection, the relay is triggered, cutting off power to the single motor on one side of the car. The other motor continues to run uninterrupted, causing the vehicle to turn sharply to the right. The car will continue in this turning path as long as the obstacle remains detected by the IR sensor. Once the obstacle is cleared, the IR sensor's output reverts, deactivating the relay. Power is restored to the stalled motor, and both motors run simultaneously, allowing the car to resume moving forward on its original path. This simple logic creates an effective autonomous avoidance behavior without requiring a programmable microcontroller.
