Five-way four-function infrared remote control circuit
Source: InternetPublisher:3228 Updated: 2010/02/01
The picture shows a five-way four-function infrared remote control circuit using MC145026 as the compiler and MC145027 as the decoder.
(a) The picture is the remote control transmitter (b) The picture is the infrared receiving and decoding circuit (c) The picture shows The specific control content that each data output terminal can be connected to. (d) The figure shows that the four data terminals of MC145027 control the volume and channel of an audio power amplifier through the four analog switch circuit CD4066.
