Solderless Breadboarding with the M5Stack
In the previous chapter, you learned about the various Snap Circuits blocks that extend the M5Stack Core operational functions. You learned about blocks that allow motion, lights, and sound to enhance the appeal to the user of an M5Stack Core. You learned how to program the LED MC using a basic procedure. The PICAXE microcontroller used in the LED MC was presented to you using an electronic circuit schematic diagram. Furthermore, you learned about the ALARM IC module and the ASIC used to produce various sound effects. With the alarm IC, you learned how to wire the Snap Circuits unit to produce sounds such as a machine gun, a siren, a fire engine, and a European siren. You learned about the snap pins for the LED MC and the alarm IC modules in the previous chapter. Lastly, an interface circuit technique for wiring the M5Stack Core to a Snap Circuits LED MC and alarm IC using a transistor relay driver circuit was presented in the previous chapter...
