A slave Arduino cannot behave like any other dedicated slave device: this is not fair. The solution is to have a library that allow me to do things in the hard way. The wire made hard. The wire more close to the hardware in a simple way. I called it the Hard Wire. Because somehow allow me to made the microcontroller to behave as. This library allows you to communicate with I2C / TWI devices. On the Arduino boards with the R3 layout (1.0 pinout), the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to the AREF pin and the additional one is on pins 20 and 21. This code essentially calls upon the Arduino library, 'OneWire', and takes the serial data taken from the sensor, and further modifies/converts the incoming data into a readable, decimal value. I modified this code so that it can perform the following. 1-Wire Information Maxim Semiconductor's 1-Wire Products. Wikipedia explains 1-wire protocol. Tom Boyd explains 1-wire protocol. Dallas Temperature Control Library. Arduino's OneWire page (warning: has buggy version) Weather Toys - community using 1-wire devices. History & Credits Jim Studt wrote OneWire in 2007, originally based on code.

The one wire Digital Temperature Sensor - DS18B20 from Maxim (formerly Dallas) is a great chip for measuring temperature in your projects. Luckily, there is a Dallas Temperature library for the arduino which makes using this sensor very easy.

The most recent version of this library can be found at
http://www.milesburton.com/?title=Dallas_Temperature_Control_Library

Download a copy of the library. In it you will find two folders

Drag and drop the DallasTemperture folder into your arduino/libraries folder

If you dont already have the OneWire library then you will need to copy that folder into the libraries folder also.

Now, before we get to the programming part, lets wire up our temperature sensor. The DS18B20 can be powered by between 3.0V and 5.5V so you can simply connect its GND pin to 0V and the VDD pin to +5V from the Arduino. However, the DS18B20 can also extract its power from the data line which means we only effectively need two wires to connect it up. This makes it great for use as an external sensor.

So we will use the 2 wire method. Simply connect both the GND and VDD pins to 0V (yes both). Then connect the DQ pin to pin 2 on the Arduino board (can be any Arduino digital pin)

A 4K7 ohm pullup resistor is required on the DQ pin to pull it up to 5V

Here is our sensor setup on a breadboard

Here's a closeup. The brown wire connects pins 1 and 3 together, and the black wire connects them both to 0V. The orange wire is our signal wire to pin 2 on the Arduino, and there is a 4K7 pullup resistor to 5V

Next, load up the sketch below and upload it to your Arduino board. Using the Dallas Temperature Library makes getting the temperature easy.

When you have uploaded the sketch, click on the Serial Monitor and you should see output like the following. The temperature is in degrees C

In Arduino IDE this is usually /libraries/
In PlatformIO this is usually <user/.platformio/lib>

The library provides an interface class, which allows communication to the RGB Matrix over NZR. Check out the examples how to use the RGB Matrix.

  • RAK14012_RGB_Matrix_Disco Light up the RGB mixed color screen as your Disco atmosphere light.
  • RAK14012_RGB_Matrix_RandomColor Light up the RGB mixed color screen using random colors.
  • RAK14012_RGB_Matrix_SevenColor Light up the RGB mixed color screen to display seven colors.
  • RAK14012_RGB_Matrix_SingleCycle Light up the LED for a single cycle.
  • RAK14012_RGB_Matrix_Strand RGB Matrix Strand.

This class provides the following methods:

Notes: Because Class RAK_RGB_Matrix Inherits from Adafruit_NeoPixel class, all functions description below will apply to RAK_RGB_Matrix. Below is the important API

RAK_RGB_Matrix pixels(uint16_t n, uint16_t p, neoPixelType t);
NeoPixel constructor when length, pin and pixel type are known at compile-time.Parameters:

DirectionNameFunction
innNumber of NeoPixels in strand.
inpArduino pin number which will drive the NeoPixel data in.
intPixel type -- add together NEO_* constants defined in Adafruit_NeoPixel.h, for example NEO_GRB+NEO_KHZ800 for NeoPixels expecting an 800 KHz (vs 400 KHz) data stream with color bytes expressed in green, red, blue order per pixel.

void begin(void);
Configure NeoPixel pin for output.Parameters:

DirectionNameFunction
returnnone

void updateLength(uint16_t n);
Change the length of a previously-declared Adafruit_NeoPixel strip object. Old data is deallocated and new data is cleared. Pin number and pixel format are unchanged.

@note This function is deprecated, here only for old projects that may still be calling it. New projects should instead use the 'new' keyword with the first constructor syntax (length, pin, type).

Parameters:

1 Wire Library Arduino Download
DirectionNameFunction
innNew length of strip, in pixels.
returnnone

void setPin(uint16_t p);
Set/change the NeoPixel output pin number. Previous pin, if any, is set to INPUT and the new pin is set to OUTPUT.

Parameters:

DirectionNameFunction
inpArduino pin number (-1 = no pin).
returnnone

void updateType(neoPixelType t);
Change the pixel format of a previously-declared Adafruit_NeoPixel strip object. If format changes from one of the RGB variants to an RGBW variant (or RGBW to RGB), the old data will be deallocated and new data is cleared. Otherwise, the old data will remain in RAM and is not reordered to the new format, so it's advisable to follow up with clear().

@note This function is deprecated, here only for old projects that may still be calling it. New projects should instead use the 'new' keyword with the first constructor syntax (length, pin, type).

Parameters:

DirectionNameFunction
intPixel type -- add together NEO_* constants defined in Adafruit_NeoPixel.h, for example NEO_GRB+NEO_KHZ800 for NeoPixels expecting an 800 KHz (vs 400 KHz) data stream with color bytes expressed in green, red, blue order per pixel.
returnnone

void show(void);
Transmit pixel data in RAM to NeoPixels.

@note On most architectures, interrupts are temporarily disabled in order to achieve the correct NeoPixel signal timing. This means that the Arduino millis() and micros() functions, which require interrupts, will lose small intervals of time whenever this function is called (about 30 microseconds per RGB pixel, 40 for RGBW pixels). There's no easy fix for this, but a few specialized alternative or companion libraries exist that use very device-specific peripherals to work around it.

Parameters:

DirectionNameFunction
returnnone

void setPixelColor(uint16_t n, uint8_t r, uint8_t g, uint8_t b);
Set a pixel's color using separate red, green and blue components. If using RGBW pixels, white will be set to 0.

Parameters:

Wire
DirectionNameFunction
innPixel index, starting from 0.
inrRed brightness, 0 = minimum (off), 255 = maximum.
ingGreen brightness, 0 = minimum (off), 255 = maximum.
inbBlue brightness, 0 = minimum (off), 255 = maximum.
returnnone

void setPixelColor(uint16_t n, uint8_t r, uint8_t g, uint8_t b, uint8_t w);
Set a pixel's color using separate red, green, blue and white components (for RGBW NeoPixels only).

Parameters:

DirectionNameFunction
innPixel index, starting from 0.
inrRed brightness, 0 = minimum (off), 255 = maximum.
ingGreen brightness, 0 = minimum (off), 255 = maximum.
inbBlue brightness, 0 = minimum (off), 255 = maximum.
inwWhite brightness, 0 = minimum (off), 255 = maximum, ignored if using RGB pixels.
returnnone

void fill(uint32_t c=0, uint16_t first=0, uint16_t count=0);
Fill all or part of the NeoPixel strip with a color.

Parameters:

DirectionNameFunction
inc32-bit color value. Most significant byte is white (for RGBW pixels) or ignored (for RGB pixels), next is red, then green, and least significant byte is blue. If all arguments are unspecified, this will be 0 (off).
infirstIndex of first pixel to fill, starting from 0. Must be in-bounds, no clipping is performed. 0 if unspecified.
incountNumber of pixels to fill, as a positive value. Passing 0 or leaving unspecified will fill to end of strip.
returnnone

uint32_t getPixelColor(uint16_t n) const;
Query the color of a previously-set pixel.

Parameters:

DirectionNameFunction
innIndex of pixel to read (0 = first).
return'Packed' 32-bit RGB or WRGB value. Most significant byte is white (for RGBW pixels) or 0 (for RGB pixels), next is red, then green,and least significant byte is blue.

void setBrightness(uint8_t b);
Adjust output brightness. Does not immediately affect what's currently displayed on the LEDs. The next call to show() will refresh the LEDs at this level.

@note This was intended for one-time use in one's setup() function, not as an animation effect in itself. Because of the way this library 'pre-multiplies' LED colors in RAM, changing the brightness is often a 'lossy' operation -- what you write to pixels isn't necessary the same as what you'll read back. Repeated brightness changes using this function exacerbate the problem. Smart programs therefore treat the strip as a write-only resource, maintaining their own state to render each frame of an animation, not relying on read-modify-write.

Parameters:

DirectionNameFunction
inbBrightness setting, 0=minimum (off), 255=brightest.
returnnone

uint8_t getBrightness(void);
Retrieve the last-set brightness value for the strip.

Parameters:

DirectionNameFunction
returnBrightness value: 0 = minimum (off), 255 = maximum.

void clear(void);
Fill the whole NeoPixel strip with 0 / black / off.

Parameters:

DirectionNameFunction
returnnone
