Arduino NANO Version 3 is the open source smallest Embedded Development board launched by Arduino based on Atmega328 SMD Package Microcontroller. It is a Surface mount Breadboard Friendly board integrated with Mini USB Port. DC Power Jack is not available on this Board, so power can be given through Mini USB Cable. It automatically sense and switch to the higher potential source of power, there is no need for the power select jumper.

Difference between Arduino Nano and Arduino Mega

There is a considerable amount of difference between the Arduino Nano and the Arduino mega as the processor used itself is different. Arduino Mega is more powerful than an Arduino Nano in terms of speed and number of I/O pins. As you might guess the size is also bigger than an Arduino UNO. Arduino Mega is normally used for projects which require a lot of I/O pins and different Communication protocols. The technical difference between Nano and Mega is shown below.

6.      Can be fully controlled with only 6 digital lines! (Any analog/digital pins can be used)

 

 

I2C Module LCD Serial Display Adapter


I2C Module is a parallel to serial converter compatible with LCD2004 and LCD1602. By using this module, LCD can be interfaced with using only 2 wires. LCD displays take 8 pins so sometimes user can get out of resources, mostly using Arduino Uno and Nano, but this device helps to save the resources as it takes only 4 pins.

 

Features

  1. Compatible with 16×2 and 20×4 LCD display
  2. Saves resources using only 4 pins
  3. LCD can be interfaced using 2 wires
  4. Easy to interface
  5. Standard 5V supply voltage
  6. Contras is adjustable

 

 

MAX30100 Pulse Oximeter Heart Rate Sensor Module :- 

Heart Rate click carries Maxim’s MAX30100 integrated pulse oximetry and a heart-rate sensor. It’s an optical sensor that derives its readings from emitting two wavelengths of light from two LEDs – a red and an infrared one – then measuring the absorbance of pulsing blood through a photodetector. This particular LED colour combination is optimized for reading the data through the tip of one’s finger.

 

The signal is processed by a low-noise analog signal processing unit and communicated to the target MCU through the mikroBUS I2C interface. Developers of end-user applications should note that the readings can be negatively impacted by excess motion and changes in temperature. Also, too much pressure can constrict capillary blood flow and therefore diminish the reliability of the data. A programmable INT pin is also available. The operates at the 3.3V power supply.

 

 

Specifications and Features:

1.      Optical sensor: IR and red LED combined with a photodetector

2.      Measures absorbance of pulsing blood

3.      I2C interface plus INT pin

4.      3.3V power supply complete pulse oximeter and heart rate sensor solution, simplifies design, integrated LEDs, photo sensor, and

5.      high-performance analog front

6.      Ultra low power operation increases battery life for wearable devices

7.      Advanced functionality improves measurement performance, high SNR provides robust motion artifact resilience integrated

8.      ambient, light cancellation high sample rate capability fast data output capability

9.      It is an integrated pulse oximetry and heart rate monitor sensor solution.
