We will make this project in two part. In the first part, we will design a remote control circuit using RF module and in the second part, we then connect a home appliance to our circuit. The circuit below is fully tested on real hardware and if you are doing this project in Proteus then you will need an RF module transmitter and receiver library. Many proteus does not have this library so check if you have this library or not if not please download from this link Rf module electronify read the instruction provided to include this library. Or alternatively, you can download complete proteus simulation file from this link Rf module simulation electronify. And the explanation is below the circuit diagram.
Before explaining last time I am telling you that “without reading the datasheet of components you are using, you cannot design an efficient circuit”. In above project, you will need a datasheet of M145026 and M145027. Please download the datasheet from this link datasheet and read it carefully. M145026 is an encoder ic and M145027 is decoder ic. The encoder read the input state and generate a unique value after pressing a button and then the value is transmitted by the transmitter. On the other hand, Receiver receives the generated value from transmitter wirelessly and the decoder detects the value generated by the encoder and then necessary action is done according to this value. That’s all concept behind this project. If you have any further question about this project please leave a comment below, I will try to answer it.
