TheArduino Leonardois a microcontroller board based on the AT32u4 . It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.


The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial and COM port. It also has other implications for the behavior of the board;

Based on Avia Semiconductor''s patented technology, HX711 is a precision 24-bit analogto-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier (PGA). Channel A can be programmed with a gain of 128 or 64, corresponding to a full-scale differential input voltage of +-20mV or +-40mV respectively, when a 5V supply is connected to AVDD analog power supply pin. Channel B has a fixed gain of 32. Onchip power supply regulator eliminates the need for an external supply regulator to provide analog power for the ADC and the sensor. Clock input is flexible. It can be from an external clock source, a crystal, or the on-chip oscillator that does not require any external component. On-chip poweron-reset circuitry simplifies digital interface initialization. There is no programming needed for the internal registers. All controls to the HX711 are through the pins.

This module can take an input voltage of between 5 and 32V DC and converts it to an output voltage between 5 and 35V DC. You may use this module to generate high voltage upto 32V from small battery packs other power sources.

Features:

  • Built-4A efficient MOSFET switches enable efficiency up to 94%; (LM2577 current is 3A)
  • High switching frequency 400KHz, can use a small-capacity filter capacitors that can achieve very good results, the ripple smaller and smaller. (LM2577 frequency only 50KHz)

Test Results:
  • Input 3V Output 12V 0.4A 4.8W (input voltage less than 5V not recommended)
  • Input 5V Output 12V 0.8A 9.6W
  • Input 7.4V Output 12V 1.5A 18W

  • Input 12V Output 19V 1.5A 28.5W
  • Input 12V Output 24V 1 A 24W

Vin x Iin x Efficiency = Vout x Iout
  • Vin Input Voltage
  • Iin Input current
  • Vout Output Voltage
  • Iout Output current

Technical Parameters:
  • Module Properties Non-isolated boost (BOOST)
  • Rectification Non-Synchronous Rectification
  • Input Current 4A (max), no-load 18mA (5V input, 8V output, no-load is less than 18mA. Higher the voltage, the greater the load current.)
  • Conversion efficiency <94% (greater the pressure, the lower the efficiency)
  • Output Ripple 50mV (the higher the voltage, the greater the current, the greater the ripple)

When using these modules remember that the output current will be a lot less than the input current, (remember - W = VA). For example, if you have a 10V output at 1A from a 5V input, the input current will be around 3.6A. The real-life maximum amount of power you can get out of these things is around 10W. If Output current is greater than 2.5A (or output power greater than 10W) use with heatsink only.

    Other Detail:
    • OLED’s are the future of displays, as they possess some of the greatest advantages over both conventional display technologies of LCD’s and LED‘s.
    • The most attractive thing about using the OLED displays is that they do not need a back-light like conventional LCD/LED screens. The organic material itself has a property known as Electroluminescence (EL), which causes the material to “glow” when stimulated by a current or an electric field. Best energy saving displays ever!!!
    • They are featuring much less thickness than LCD displays with good brightness and also produce better and true colors. 
    • This OLED Display Module is very compact and will add a great ever user interface experience to your Arduino project. The connection of this display with Arduino is made through the I2C(also called as IIC) serial or SPI interface.
    • The 0.96″ OLED Display Module produces blue text on black background with very good contrast when supplied with DC 2.8V supply. The OLED Display Modules also offers a very wide viewing angle of about greater than 160°.
    • Setting up SPI/I2C Connection with GMS096A OLED Module
    • Being a new entry into the market, only limited resources are available on this small piece of a miracle (GMS096A). I2C/SPI configuration always demands helpful resources as in any case. For the SPI setup, the module comes in 4 wire SPI configuration by default and to make it work with the Arduino you can use these libraries from Adafruit.
    • For the I2C setup, it demands a little bit of work on the module, let us start with resoldering the resistor from position R3 to R1 and then short the R8 resistor with some soldering tin (0 Ohm resistor). The R6 and R7 pullup resistors are already soldered, nothing to do there. Once done, the module is ready for I2C communication! The CS Pin is not necessarily needed, so just connect it to GND. The DC Pin selects the address. For standard address wire it to GND. The RES-pin needs a low pulse at startup and a high voltage during operation (as in SPI mode), a 100nF capacitor to GND and a 10k resistor to VCC would be ideal.

    Features:
    • No need of the backlight
    • The display is self-illuminating
    • Power requirement is low
    • They are offering the large viewing angle
    • Full Compatible with Arduino
    • Factory configured for SPI protocol (can easily change to IIC)
    • Better performance characteristics than traditional LCD and LED displays.
    • Only Need 2 I/O Port Control

    The MT3608 2A Max DC-DC Step Up Power Module Booster Power Module is a low-cost module that can step-up a 2 to 24V input voltage up to a 5 to 28V output at up to 2A.

    DC-DC boost converters step up the input voltage to a higher voltage while also stepping down the available current since the module cant output more power than its inputs.

    This boost converter is adjustable and capable of outputting a voltage in the range of 5.0 to 28V at a continuous current of up to 1.5A depending on input/output voltage settings with 1A available with most settings.

    Since it is a boost converter, the input voltage must be lower than the output voltage.

    The device is able to use low ESR bulk ceramic capacitors rather than electrolytic caps which avoids long-term aging concerns and contributes to the compact packaging.

    The MT3608 converter IC has over-current and thermal limiting features built-in to safely shut the device down if driven too hard.


    Voltage Adjustment:-

    The module has a single-turn potentiometer for adjustment of the output voltage.

    Turning the pot CW decreases the output voltage while turning it CCW increases the output voltage.

    The upper limit of the adjustment range will depend on the input voltage and the load. With a 9V input for instance, at 1A, the upper voltage limit will be approximately 20V.


    Module Connections:-

    These are compact boards with 4 solder pads for making connections.

    1. VIN+ = Input Voltage
    2. VIN- = Ground
    3. VOUT+ = Output Voltage
    4. VOUT- = Ground. Connected to VIN- on the module.

     

     

    Note:-
    • The input voltage should not exceed the maximum input voltage.
    • Peak current output current is not more than 2A for input & output.
    • Please be noted that the output voltage should be higher than the input voltage.

    Features :-
    1. Its efficient by up to93%.
    2. It can source a good amount of current.

      Model Name/NumberTurbidity Sensor

      The turbidity of water refers to the degree of turbidity caused by suspended substances such as silt, clay, organic matter, plankton and microorganisms contained in the water. Industrial-grade turbidity sensors or turbidity meters are expensive, and the cost is too high in the design of electronic products. Therefore, we have selected a turbidity sensor that is widely used in household appliances, washing machines, and dishwashers. The sensor uses optical principles to comprehensively judge the turbidity through the light transmittance and scattering rate in the solution. Inside the sensor is an infrared tube. When light passes through a certain amount of water, the amount of light transmission

      depends on the degree of dirtiness of the water. The dirtier the water, the less light it transmits. Light

      The receiving end converts the intensity of the transmitted light to the corresponding current size. The transmitted light is more and the current is larger. On the contrary, the transmitted light is less and the current is smaller.

      The turbidity sensor module converts the current signal output by the sensor into a voltage signal and performs AD conversion data processing through the single-chip microcomputer. The re-modelling module has analogue and digital output interfaces. The analogue quantity can be sampled and processed by the single-chip A/D converter to know the current water pollution. The digital value can be adjusted through the potentiometer on the module to adjust the trigger threshold. When the turbidity reaches the set threshold, the D1 indicator will be lit, the output of the sensor module changes from high level to low level, and the single-chip monitors the change in level To determine whether the turbidity of the water exceeds the standard, so as to warn or link other equipment. The module is inexpensive, easy to use, and has a high measurement accuracy

      It can be used to measure the degree of water pollution of products such as washing machines and dishwashers; it can also be used in industrial field control, environmental sewage collection and other occasions that require turbidity detection and control.

      The composition of the turbidity sensor module is shown below. The module is connected to the turbidity sensor through the 3Pin XH-2.54 connector. Adjust the knob of 10K blue potentiometer to adjust the trigger threshold of digital output.

      The module pin definitions are as follows:

      1. VCC: Positive supply voltage, 5V cannot be used 3.3V
      2. AO: analogue signal output, output voltage range 0~5V
      3. DO: digital signal output is less than the set value and outputs high level; greater than the set value and outputs low level
      4. GND: negative supply voltage
