Summary
In this chapter, you learned how to use the pulse width modulation and analog-to-digital converter subsystems with PyBBIO and Adafruit_BBIO. You learned how to use PWM to set the brightness of LEDs and drive servo motors. You also learned how to measure voltages with the ADC, and how to use voltage dividers and buffers to measure voltages greater than 1.8 V.
In the next chapter, you will learn to incorporate buttons and potentiometers into your circuits to receive user input.
