    I got two MC's the ATTiny84 (7PIN) and the PIC16F877-20/p
    &
    USB to Serial as shown here.

    here it shows that Pin 1 & 2 on the USB to Serial device is the RX/TX and connects to PIN 2/3 on the PIC16F877-20/p Microcontroller as shown here
    http://guides.machinescience.org/mod/book/view.php?id=1316&chapterid=4808

    but when I look up how to connect the USB to Serial RX and TX to this ATTiny84 chip, what the hell am I looking for? how do I know which port to connect the TX/RX?

    and do those also use the same wires to Flash the Chip with instructions?

    How can I pull the instructions on the chip currently and read what is already on there?

    Thanks! Many questions, Many ;)
