This module is intended to conduct input / output interface experiments. It has 8 SPDT switches connected as input and 8 LEDs as output port. The student learns how to input 8-bit data from an external hardware, and display the same on external 8 -bit LED port. At the time of project design or prototype development, this can be used as a development module, whenever I/O operation is to be performed. It helps in validating the designed program. An external power supply of + 5V @ 250mA is required.

Specifications:

• 8 numbers of SPDT switches.
  
• 8 numbers of high bright LEDs.
  
• Electronic Design Experimenter Model EDE-1 is recommended.

Note: This experimental module can be interfaced to all Microprocessor trainers, Micro control trainers or IBM PC Add – on card Model: IBL-IBR-1.
