I am trying to develop a system where I will send a specific signal to a microcontroller by pressing any of around 100 different buttons and for each key, the microcontroller has a fixed task that it will accomplish. A good example of my system can be a Bluetooth keyboard with a pc. For example, by pressing 'A' we get written A in pc screen. Another example is an IR-based remote system with a TV where each key gives a different channel.
Note: I am not talking about android based communication like smartphone and Arduino connection with HRC Bluetooth module. In my system, no smartphone will be used.
1. Now I want to know how can I do that? Please specify with Bluetooth transmitter, receiver name, and a schematic diagram if possible.
2. If you have any tutorial that may help me, I will love it if you share.
3 IR or Bluetooth, which one will be cost-effective and more efficient?
