How it works
The PICAXE is programmed through pins 2 and 3, which are
connected to the computer’s serial port (or to a USB-to-serial
adapter). Resistors R1 and R2 and a DB9 connector are all
that are needed to connect your computer to the PICAXE for
programming.
Infrared pulses are generated by pressing a key on the TV
remote control. These are received by the IR receiver IC and
sent to the PICAXE through pin 8.
6. The small Vishay TSOP4838 chip receives the
infrared codes.
