ELET 2103 Digital Systems 4 Title: The title says what you did. It should be brief and describe the main point of the experiment or investigation. Equipment/ Materials : Breadboard Power supply Oscilloscope 300Ω resistor (5) 10KΩ resistor (2) LEDs (5) 74LS00N 74LS04N Procedure: To begin our circuit, we placed the 74LS00N and 74LS04N on our breadboard. We then followed the circuit diagram (Fig. 1) and connected the correct LEDs and resistors to each part. Each resistor was then connected to the same VCC in order to all receive power. Two wires were placed from R2 and R3 to ground to represent Switch A and Switch B. Our power supply was then turned on to 5V. At first, we were only receiving power to one LED, LED X, as seen in figure 2. We then moved our circuit around (Fig. 3) to attempt to get the correct output, but we were unsuccessful. Numerical Data / Analysis:

ELET 2103 Digital Systems 6 Figure 3 Conclusion : In the end, our circuit did not give the correct output. After many attempts, we are to assume that it could be our breadboard or other equipment. This experiment taught us that the 74LS00N and 74LS04N have multiple inputs and outputs, which meant that we would only have to use 1 of each instead of 2 and 5 of each as shown in the circuit diagram (Fig. 1).
