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 4 -bit LED port. Each BIT of input or output is identified as an independent 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 5V DC @250mA is required or +5V DC power supply Model SP5 is recommended.

Specifications:

• 8 numbers of SPDT switches.
  
• 4 numbers of LED indicators.
