Knowledge of sensors are very essential part of robotics.And IR sensor  is very useful if you are tying to make a obstacle avoider robot or a line follower. In this post we are going to make a simple IR sensor which can detect a object around 6-7 cm. or you can change range of sensor to 1-2 cm if you are using for line follower.

In this tutorial i am going to show you how to setup your project  in Keil for 8051 (AT89s51) to simulate and debug your code. This is one of the most important tutorial for beginner who just start learning 8051. Because Keil is the best IDE to compile,debug and simulate your program.  And most of 8051 programmer you this tool so you get lot of help about this on internet. In this tutorial i use Keil v4.0 but it is same for all version or you can download lates trail version from here

  finding some parts in multisim is really tough work because multisim  not provide all general purpose component like 7085 and other voltage regulator. one more  bad information is that manufacturer of these component also not provide any PSPICE because output of these component are predetermined and not changed according to the circuit.

counters are used in most of all digital devices like digital clock, camera, CD/DVD recorder, mobiles etc. to count sequence in the form of pulse. and many project required a counter for counting sequence according to need of project. So in this part we are going to make a Decade Counter using CD4017 IC

Multisim is best simulator for electronics circuits and MCU devices with high accuracy. but there is a problem for microcontroller with mutisim, that is they  not give any user manual for 8051 with c language. this post give a basic idea how to use c language in multisim for 805x mcu devices.
