DESIGNING OF MICROCONTROLLER 8051 BASED LEARNING MEDIA OF CONTROL

On this occasion the author developed Microcontroller 8051 based Active Learning Media of control using 8051 microcontroller simulator MCU 8051 IDE on Windows 7 (MCU 8051 IDE can basically run on various operating systems)[3] to support the implementation of active learning in higher education. Instructional media developed in the form of a controlling simulation program in C language with SDCC compiler-Small Device C Compiler. This simulator can be downloaded freely on www.sourceforge.net[3] and SDCC can be downloaded for free as well on http://sdcc.sourceforge.net/ [7]. The developed simulator will mimic a control system consist of an input switch connected to P0.0 that imitate an input from a sensor and an alarm as an output in the form of a Virtual Common Anode Seven Segment Display that will display a character “L” or “H” in accordance with the input from the sensor; this virtual output device connected with P1 of 8051. Based on the author class observation, this simulator has been successfully enhanced the participation of the students in the learning process, allowing the author to apply his learning strategy properly and successfully overcome the lack of funds to meet the need of spending for equipments [6]. The simulation program has also been successful in reducing errors in building a real devices (reducing the costs of production).
