For example, after writing a simple program using assembly / C- language, students can load the program hex file into the micro-controller using ISP and they can easily connect the microcontroller to related interface circuit through the connector to see the result immediately. The 8051 microcontroller perform single task at a time which create an effective learning environment for the student. The experimental board is multi-module- based where the 8051 micro-controller is on the main module and other modules are related to interfacing application such as the 16X2 LCD display, 7-segment display, dc motor speed control, DAC, etc. This paper discusses the development and use of multi-module 8051 microcontroller experimental board for microcontroller course for teacher and student of different disciplines in science and engineering. Laboratory session is one approach that has helped students to understand the subject when they are exposed to the hardware and software. Learning the microcontroller has become necessary not just for engineering but also many other disciplines, such as computer science, electronics and physics. A microcontroller is playing an active role in an embedded system.
