Use your favourite internet search engine. Hint: try keywords like "infra-red", "infrared", and "RC5"
Hello, in the past (1998) we developed an IR Receiver with an 8051; we used optic receiver modules from KODENSHI, model HC-337 and SIEMENS (now INFINEON), model SFH507. Try a GOOGLE search to find them or equivalents. Bruno
