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 ...

An IR (Infrared) sensor is a device that detects infrared radiation emitted by objects. It is commonly used for proximity sensing, object detection, and motion detection applications. IR sensors are ...

Explore a range of Arduino-based DIY projects, from creating contactless thermometers to developing smart home automation systems, obstacle-avoiding robots, ... A TSOP1738 IR sensor is used to decode ...

For first part, upload IR_decoder.ino code to Arduino. Connect the circuit as shown in Fig. 1. MP3 Vire (21-key) remote was used during testing. Compile and upload the code to Arduino. Now, point the ...

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

In this project, we are using IR based wireless communication for controlling home appliances. In this project, Arduino is used for controlling whole the process. We send some commands to the ...
