The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52.

In this project, an IR sensor is used as an external interrupt to Arduino. In Arduino Uno, digital pin 2 & 3 are the interrupt pins, so connect the Out pin of IR sensor to the 3 rd pin of Arduino.
