2 Lab

  1. Place a block of 8 DIP switches on your breadboard, see Figure 2.
  2. Connect each lead on one side to VCC.
  3. Put a 1k resistor from each of the leads on the other side to ground. Also on this side, place a row of 8 pin headers so that you have outputs from all of these switches.

  4. In order to be able to connect to the board you will need to solder pin headers to one of the prototyping areas (see Figure 3). Use area $ A$ . For now solder the first two rows (Figure 4).

  5. Use Figure 5 for the pin labels.

  6. Now that you have all the hardware setup. Design the BCD-to-seven-segment decoder and test it using different inputs using the dip switches.
  7. Implement your multiplexer program that you developed in the prelab.
