This sensor can be used to send and receive infrared messages.

The sensor is made up of three parts all located across the front of Edison: two infrared LEDs (one on the right and one on the left) plus an infrared receiver in the middle. Because it detects visible light, the line sensor can also be used as a light sensor when Edison is in different positions or being used as a part of an engineered creation.Įdison’s infrared (IR) light sensor is the sensor that lets Edison emit and detect infrared light. Thanks to its scope of use and the various ways it can be programmed, the line tracking sensor is excellent for teaching concepts such as algorithms. The robot can be made to follow a line, stay inside black borders or change its behaviour each time it encounters a change in surface. Edison can be programmed to react based on the surface it detects, allowing for a wide range of behaviours. The robot can use these light readings to determine if it is on a reflective (e.g.

The more light that is reflected back to Edison, the higher the light reading. Edison stores the value of the reflected light as a light reading. The light sensor then measures how much of that light bounces up from the surface. The line tracking sensor works by shining light from the red LED onto the surface below the robot. The line tracking sensor is made up of two parts: a red LED and a visible light sensor. The sensor is located on the bottom of Edison, near the power switch. The line tracking sensor is the sensor that lets Edison see the difference between dark and light surfaces. Obstacle detection can also be used in creative, autonomous programs, such as getting the robot to complete a 3D maze. The robot can be programmed to respond when it detects an obstacle, for example, by backing up and turning away.īecause the IR light sensor can be used to detect both the presence and relative location (on the right, on the left or straight ahead) of obstacles, it is ideal for teaching conditionals and branching. Edison’s infrared receiver detects the reflected light, telling Edison that there is an obstacle. If that infrared encounters an obstacle, like a wall, the light is reflected back towards Edison. One way we can use Edison’s infrared light sensor is to detect obstacles.Įdison can emit infrared light from the two infrared LEDs. The two infrared LEDs can emit IR light, which is invisible to humans, but can be detected by Edison using the infrared receiver on the front of the robot. The robot’s infrared light sensor is the sensor that lets Edison emit and detect infrared light. The system that allows Edison to detect and react to obstacles works using infrared light.
