Raspberry Pi GPIO header

The following screenshot is a chart of the GPIO pins of the Raspberry Pi Zero. In this case, we will use the SPI configuration interface (SPI_MOSI, SPI_MISO, SPI_CLK, SPI_CE0_N):

You need to connect the following pins according to the next description:

VDD to 3.3 volts
VREF to 3.3 volts from the Raspberry Pi Zero
Pin AGND to GND
Pin CLK (clock) to GPIO11 of the Raspberry Pi
DOUT to GPIO9
Pin DIN to GPIO10
Pin CS to GPIO8 and the pin
Pin the MCP3008D GND to Ground

This connection is represented in the following figure:

Reading the data with a Python script

In the next section, you will create the MCP3008.py file; you need to follow the next steps:

Open the terminal on your Raspberry Pi Zero.
Enter the interface in...
