10, Test conclusion
Arduino UNO test results:
Under the condition that the infrared obstacle avoidance module is powered on, adjust the potentiometer of the infrared obstacle avoidance module with a small screwdriver, so that the finger is about 20mm away from the infrared obstacle avoidance probe, the sensor signal indicates the blue light is on, and the infrared obstacle avoidance module signal indicates the blue light is off when the finger is about 20mm away from the probe.Note: The infrared emitting and receiving probes of the infrared obstacle avoidance module are greatly interfered by the ambient light, please do not debug in a strong sun environment.
The infrared obstacle avoidance module utilizes the working characteristics of infrared. When the infrared obstacle avoidance module sensor detects an obstacle, it outputs a low level (0); the LED light is turned on. When the infrared obstacle avoidance module sensor does not detect any obstacle ahead, it outputs a high level (1), and the LED light is off.
