The gesture hardware architecture
There are just three major components that we need to be concerned about within the hardware architecture:
- The MicroPython development boards
- The APDS-9960
- The LEDs
Just as in the previous projects, we can power the MicroPython board through a USB connector, at least during development. As we saw in the last lab, if you are using the STM32 IoT Discovery node with the Arduino prototyping board, there are +5V and +3V output headers. The development boards for the APDS-9960 from Adafruit and SparkFun can take 3V, so they can be powered directly from the MicroPython board. In most cases, it also makes sense to power the LEDs through +3V and then use a General Purpose Input/Output (GPIO) pin to control the state ...
