infrared receiver

8 Channels Infrared Receiver (Code Learner) With Arduino UNO

The IR receivers typically work in 37 KHz frequency. The “8 Channels Infrared Receiver” project receives the IR signal via HS0038A2 (or similar modules), which the module filters the 37 KHz signal and sends the data in 1 Kbps speed to the ArduinoUNO board. The Project’s Download Link: Infrared Receiver Source Code For Arduino UNO…
