Installation¶

• Install "Arduino IDE":https://www.arduino.cc/en/Main/Software
• Start, and define your Arduino Folder (for example, <tt>Arduino</tt> in your home directory)
• Install Arduino board definition according to guide, depending on your platform:
  • Adafruit Feather nRF52 Arduino Support Guide (nRF52832 is used) (Troubleshooting)
  • Using the Huzzah32/ESP32 Feather with Arduino
• Test board with the "Examples/Digital/Blink" sketch: should blink onboard LED
• Install base libraries (Adafruit Howto)
  • Open Library Manager: Sketch -> Include Library -> Manage Libraries
  • Install and test (depending on what you need):
    • Motion/Orientation Sensor: Adafruit Sensors and Adafruit BNO55 (Docs)
    • RGB LEDs: Adafruit Neopixel (Docs)
      • In example sketches, change/add our LED Specifics:
        

        #define LED_PIN    A3
        #define LED_COUNT 2
        

      • On the Adafruit ESP32 Feather, Pin A3 is not output capable (you will see according errors in the serial monitor); use another pin (e.g., 21) and connect it to A3 (which will be input-only). This is expected to be fixed in a future revision.
    • LRA Haptics Driver: Adafruit DRV2605 (Docs)
      • The example sketches need to be modified for LRA actuator type and to explicitly enable the DRV2605, add/modify setup() to contain:
        

          // before drv.begin()
          pinMode(A1, OUTPUT);
          digitalWrite(A1, HIGH);
          // after
          drv.selectLibrary(6);
          drv.useLRA();
          // todo: drive voltage!
        

    • Real Time Clock: SparkFun Qwiic RTC RV1805 Arduino Library (Docs)
