I am trying to send data back and forth between my PC and a PIC16F877 microcontroller. Previously I would read and write data from the RS-232 serial port on the PC and use the Tx and Rx pins on the PIC. This worked fine. Now I want to be able to send bytes of data to the PIC via Wi-Fi. I'm not sure what I need in order to accomplish this task. Do I need additional hardware and software? Could someone point me in the right direction? Thanks for any help.
