I'd like to build a wireless joystick for one of my machines. It's a very simple thing using only discrete switches. The type of joystick that I'm planning to use looks more or less like this:
I've already searched Digikey for wireless modules, but I can't make heads or tails of it. They all have an SPI, UART, are WiFi or Bluetooth, or have some other serial interface output that's too complicated to implement.
Is there a way to build a simple transmitter and receiver pair (or use an already made module that I have yet to find) that will transmit the state of up to 8 switches without having to use an MCU to read/control it?
I'd like to transmit the state of up to 8 switches in the joystick, thus activating up to 8 outputs at the receiver.
Distance is not that important, up to 10m would suffice. Also, battery life is not that important either, since it would be used sporadically.
