Push button circuit setup

For this exercise, we will need:

• 4-pin push button: A push button is an electronic component that is attached to two points in a circuit. It is also called a tact switch. When it is pressed, it joins these two points and the circuit is completed. The circuit is disconnected when the button is not pressed.

• Male-to-male jumper wires: We need jumper wires to connect BeagleBone and components through a breadboard.

• Half-size breadboard: A breadboard is needed to create a solderless circuit.

Power off the board and attach the components to BeagleBone as shown in the preceding diagram.

Circuit analysis

Let's see the analysis step by step:

1. The 4-pin push button is divided into two sides. Within the first side, pole 1 and pole 2 are already connected. Another side has pole 3 and pole 4 connected. But these both sides are not connected to each other. When the button is pressed, the pole 1 and pole 2 side gets connected to the pole 3 and pole 4 side.

2. Pin P9_3 and P9_4 are not regular...
