Under Arduino, the FLASH SCK pin is #38, MISO is #36, MOSI is #37, and CS is #39. This way you don't have to worry about the SPI flash colliding with other devices on the main SPI connection. The SPI Flash is connected to 4 pins that are not brought out on the GPIO pads. In CircuitPython you can access it with something like dot = adafruit_dotstar.DotStar(board.APA102_SCK, board.APA102_MOSI, 1, brightness=0.5)

In CircuitPython, the LED is used to indicate the runtime status. The DotStar is also used by the bootloader to let you know if the device has enumerated correctly (green) or USB failure (red). The DotStar is powered by the 3.3V power supply but that hasn't shown to make a big difference in brightness or color. The DotStar is connected to pin #40 (clock) and #41 (data) in Arduino, so just use our DotStar library and set it up as a single-LED strand on pins 40 & 41. #13 - GPIO #13, can do PWM output and is connected to the red LED next to the Reset button.#9 - GPIO #9, also analog input #25 and can do PWM output, or I2S data channel 0.You can use this with our NeoPixel DMA control library to automatically write NeoPixel data without needing any processor time. This is a special OUTPUT-only pin, that is level-shifted up to Vhi voltage, so its perfect for driving NeoPixels that want a ~5V logic level input. There's no pull up on this pin by default so when using with I2C, you may need a 2.2K-10K pullup on each to 3.3V SDA and SCL - these are the I2C hardware interface pins.This pin can also be an analog input (Analog #21) or I2S bitclock

#ARDUINO NANO PINOUT INTERRUPT INSTALL#
Just search for “rf24” and find and install the one by “TMRh20, Avamander”. We can also install this library directly from the Arduino IDE Library Manager.
#ARDUINO NANO PINOUT INTERRUPT DOWNLOAD#
Once we connect the NRF24L01 modules to the Arduino boards we are ready to make the codes for both the transmitter and the receiver.įirst we need to download and install the RF24 library which makes the programming less difficult.

As I already mentioned, each Arduino board has different SPI pins, so keep that in mind when connecting the modules to your Arduino board.
