So I removed this servo and IR sensors and use 3 ultrasonic sensors. With ultrasonic sensors, you can measure distance and use that information to navigate and follow a human target. Here’s a general ...

How It Works: The HC-SR04 Ultrasonic Sensor continuously measures the distance of objects in front of it. If an object is detected within the predefined range (e.g., less than 10 cm), the sensor sends ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Inside the light is an Arduino Nano, which reads from the ultrasonic sensor mounted underneath the enclosure and lights up the appropriate LED depending on the car’s distance.
