In this section, we will create our APA102 circuit, as shown in the following diagram. We will do this on our breadboard in two parts:

Let's get started on the first part, which will be to place the components and wire up the low-voltage side of a logic level converter:
Figure 8.5 – APA102 LED circuit (part 1 of 2)
Here are the steps to follow. The step numbers match the numbered black circles in Figure 8.5:
- Place the logic level converter (logic level shifter) into the breadboard, positioning the low-voltage side toward your Raspberry Pi. Different logic level converters may have different labeling, however, it should be clear which is the low-voltage side. In our illustration, one side has an LV (Low Voltage) terminal while the other has an HV (High Voltage) terminal, which distinguishes the sides.
- Connect the negative rails on the left-hand side and right-hand...
