SR Latch
SR Latches are one of the building blocks for computer memory, which consists of a "Set" and "Reset" inputs, hence the name "SR" Latch. It comes with either 2 NOR gates or 2 NAND gates, and the circuit is able to remember a state until the reset signal is pulled high.

The Schematic
Figure 2 shows the schematic of the SR Latch of both NAND & NOR gates. The output of the gates are connected to an LED respectfully. One of the inputs are connected to a push button, which has a 1k pull down resistor. The connection is represented in figure 1, where the outputs of the gates is connected to the inputs of the next gates.

Testing
Figure 3 shows how the circuit is behaving. In the video, I've explained what the LEDs and the buttons are representing, and also how the circuit was behaving.
