How to Make an Ultrasonic Nervous Robot
In this episode of the Learning Circuit Karen creates another robot! This robot has three ultrasonic distance sensors in its mouth, two micro:bits that make up eyes, and an Arduino as its brain. The sensors detect when something steps in front of the robot, and as the object moves left and right, the eyes of the robot will follow it. Not only can the robot detect when an object is in range, it can detect when that object gets too close and it will look down at the object to follow it moving. Check out the video to see Karen break down the code and show how she built the robot.
