Abstract :

This paper presents the design and development of a microcontroller based color - coded - resistor reader. The device is intended to be used for giving the exact value with the percentage tolerance of a color coded resistor when the colors on the resistor are entered to the device using a keypad. Microcontroller (PIC) IC 16F887 is used as the brain of the system. The PIC is programmed using ASSEMBLY programming language. Discrete and integrated electronic circuit (IC) components are used to design and implement the system. Also an effort is made to ensure good reliability as well as cost effectiveness for the designed system to be reliable and affordable to everybody. The device developed was found to be functioning satisfactorily when tested.
