Found a bug in the function that send the JSON string to the client. Fixed, but we haven't confirmed if the UI gets the string with the right format.
Added initial code to process connections.
Finished codding the procConnMsg() function. We need to work on the function that will actually send the data from the source to the target pin.
Added some code to sum analog and digital values to outpins connected to it input pins.
This code enables pin 13 and turns it on. It also connects A0 with ~3 and controls its output based on A0's input.
Fixed a bug where connecting two input pins to an output pin, disabled other pins.
