The Arduino Uno IR Sensor detects infrared (IR) radiation emitted by objects. It typically includes an IR transmitter and receiver pair, with the receiver detecting reflected IR light. This enables ...

Note: A compact analogue reflectance sensor such as the CNY70 was not used in the Arduino Uno experiments described. Instead, a homemade sensor was assembled using a single infrared LED (IR333C) and a ...

Presence of doctor is essential for proper patient care. But he cannot be present on each and every place to provide medication or treatment. So remote monitoring of a patient is the right solution.

6. Line Following Robot The line follower robot is a very interesting, easy to make autonomous robot. As the name suggests the line follower robot will follow the line drawn on any surface. To build ...

When a finger or other object touches the surface, it causes the IR light to scatter in many directions. Some of this light is directed down into the screen, towards an array of 64 IR sensors.
