Hello and thank you in advance for any help you may be able to give me.
I want to connect a simple switch to a serial port so that read the com port and determine the state of the switch.
Ultimately I want to connect the switch to a serial port on a bluetooth module and send a character to indicate that the switch is closed (at some reasonable sample rate, say 1hz or less). Because I am going to use a serial port over bluetooth, I think I need to actually use the TX/RX pins.
If someone could point me in the right direction it would be very helpful
Thank you
