Simple circuit of object counter using Arduino

This circuit can count number of persons entering a premise or number of objects passing in front of an IR sensor. The code works very nicely and fully tested in our lab. Note that a buzzer for short beeps is connected at pin-2 and the IR sensor is connected at pin-5. The delay in second "if" conditional statement is used to avoid accidental triggering of the sensor.

White Line Following Robot using 8051 Microcontroller

White Line Following Robot using 8051 Microcontroller

Lab tested code of White line following robot using 8051 MUC. When there is black below an IR sensor, its output is binary-1. When there is white below an IR sensor, its output is binary-0. This code is suitable for OVAL SHAPED SIMPLE WHITE TRACKS. For complicated white tracks i.e. having many steep turns, USE POWER TURN INSTEAD OF SOFT TURN.
