M5Stack and Arduino

In the previous chapter, you learned the various electronic interfacing circuits that extend the M5Stack Core operational functions. You learned the various electronic interfacing circuits that allow input and output (I/O) control of electrical DC motors, discrete LEDs, and littleBits electronic modules. The littleBits electronic modules, such as a slide dimmer and bar graphs, are devices that can be operated with the M5Stack Core. You learned to program the M5Stack Core using the UiFlow Blockly code programming environment. Digital input circuits using a series resistor and a switch were discussed in the previous chapter. Discrete transistor switches using negative-positive-negative (NPN) and positive-negative-positive (PNP) configurations allow the operation of an electrical DC motor. You learned about these electronic interfacing circuits by reviewing the circuit schematic diagrams provided in Chapter 5.

In this chapter, you will learn how to enhance electronic...
