Complete Robot after fixed the error.

After troubleshooting done and some of faulty error has been fixed. We finally met with our goal. all the effort gave us the good result for our robot assignment, thanks also to our lecturers for their recommendations and solutions. Finally, the robot is  working fine as we planned and can move according to the black tape without any problem.

Problem fixed.
1. Sensor
    We change the sensor from 3 sensor to 5 sensor because 3 sensor is not enough for the robot to            detect the curve or junction of the tape.
2. PWM code.
    We also adjust the speed of the motor so that the sensor can detect and measure the tape correctly.
3. Robot's body.
    We also made some modification to the robot's body so that the robot will move smoothly.

IC Selection

Image
We have done some reseacrh regarding IC selection on which one should we choose between AT89C52 or AT89S52. During our simulation we used AT89C52 and 8052. We have observed the power consumption and connection port between these IC and other configuration.  AT89S52 The 89S52 has 4 different ports, each one having 8 Input/output lines providing a total of 32 I/O lines. Those ports can be used to output DATA and orders do other devices, or to read the state of a sensor, or a switch. Most of the ports of the 89S52 have 'dual function' meaning that they can be used for two different functions. The first one is to perform input/output operations and the second one is used to implement special features of the micro controller like counting external pulses, interrupting the execution of the program according to external events, performing serial data transfer or connecting the chip to a computer to update the software. Each port has 8 pins, and will be treated from...
