In this chapter, you learned how to use the MCP3008 ADC converter and also how to use a temperature sensor using Raspberry Pi Zero. We explored the GPIO port and the various interfaces it features. We looked at the various things we can connect to the Raspberry Pi using GPIO.
In the next chapter, we will dive into more hardware acquisition, connecting different kinds of sensors to our Raspberry Pi Zero and Arduino boards. This will help you make real measurements in your projects. That’s very interesting—keep at it!
