Was planning to get this done ,
Handheld remote control to control lights , fanregulator in a room in India.
India : 230 V , AC supply , I think limit is 5A.
What would be an ultra low cost method for this.
What are the IC's , or PCB assemblies required or MCU.
Assuming this is to be done on a commercial scale ,
the casings , rubber buttons etc can be made available ,
how / what do you call and source the electronic chips / parts.
1.Modular Switches , most common in India.
2.External type , one single picture.
Please do reply , am trying to learn.
Thanks
Photographs attached.
