Overview:-

The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a 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 Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila.

The Mega 2560 is an update to the Arduino Mega, which it replaces.

This is D1 Mini V2 NodeMcu 4M Bytes Lua WIFI Internet Of Things Development Board Based ESP8266, it is a mini WIFI board based on ESP-8266EX. 11 digital input/output pins, all pins have interrupt/PWM/I2C/one-wire supported(except D0) 1 analog input(3.3V max input) and a Micro USB connection.

The development board features WiFi-SoC ESP8266 and is made for fast Internet-of-Things (IoT) prototyping. It is flashed with the latest firmware version and can be set up and programmed right away with the onboard micro USB connection. With only a few lines of code, the NodeMCU Dev Kit connects to your local network and ready for control by other network members like computers and smartphones.

The d1 mini is an ESP8266 development board that is compact, versatile and very easy to use with the Arduino IDE. It supports natively by the Expressive SDK.

1. Use BRT (Bias Resistor Transistor)
2. Easier into flash mode.
3.  30% increase in radiating area
4. Good stability.

The Digispark compatible development board is an ATtiny85 based microcontroller. Similar in design to the Arduino line, only cheaper and much smaller. There is a whole host of available shields to extend the functionality.

Those familiar with the Arduino will appreciate the compatibility with the Arduino IDE. This is a great way to jump into electronics, or perfect for when an Arduino boards is too big or too much.

The board features an industry standard USB Type-A plug which fits into standard USB Type-A receptacles.

The Arduino Nano is a microcontroller board, based on the ATmega328P microcontroller by Atmel. The Atmega328 comes with built-in bootloader, which makes it very easy to flash the board with your code. Like all Arduino boards, you can program the software running on the board using a language derived from C and C++. The easiest development environment is the Arduino IDE. The Nano is the smallest board of the Arduino boards but has nearly the same datasheet like the Arduino Uno. Only the power jack is missing and instead of a standard USB port the Nano has a Mini-B USB plug.

The Arduino Nano is the smallest microcontroller in the Arduino family and has therefore the lowest number of pins and connections. But in my opinion the Nano is very suitable for projects where you do not need a wireless connection.

The Nano has one 3.3V and two 5V power pins of which one is the VIN pin. With the VIN pin you can supply the Arduino Nano with a voltage between 7V-12V to run the microcontroller on battery for example. All three power pins provide a maximum currency of 50 mA. You can close the circuit with two ground pins.

The microcontroller has 8 analog pins with a 10-bit analog-to-digital converter (ADC). The ADC converts the input voltage to a signal between 0 and 1023. There is also the possibility to use the analog pins as output with the function digitalWrite(Ax).

There are in total 14 digital I/O pins which can be used with a maximum currency of 40 mA if you are not using the serial ports RX0 (UART -> In) and RX1 (UART -> Out) and do not use the Serial.begin() function in your Arduino script. If you use the serial ports, then you have in total 12 digital pins (D2…D13) that can be used like you see in the pinout picture. If you want to create a PWM signal for example to control the speed of a motor, there are 6 of the 13 digital pins, which are PWM ready.

You can use pin 2 and 3 as interrupts if you want to monitor an input during the runtime of the whole Arduino script.

The typical communication standards (SPI, I2C and UART) are also available on the Arduino Nano.

Arduino Nano R3 Power Supply

The Arduino Nano board has different voltage levels, that we have to know before we can dive into the possibilities to supply power to the microcontroller. The following picture shows a schematic of the voltage levels on the Arduino Nano as well as the voltage levels and the maximum currents defined by the components.

The main microprocessor for the Arduino Nano 3 is the ATmega328p.

The ATmega328p has an operation voltage of 5V, a minimum voltage of 2.7V and a maximum voltage of 6V. Therefore the two voltage regulators have an output voltage of 5V equal to the operation voltage of the microprocessor.

The ENC28J60 is a stand-alone Ethernet controller with an industry standard Serial Peripheral Interface (SPI). It is designed to serve as an Ethernet network interface for any controller equipped with SPI.

For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 16 bit converter.

The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115's connected on a single 2-wire I2C bus for 16 single ended inputs.

To get you started, we have example code for both the Raspberry Pi (in our Adafruit Pi Python library), Arduino (in our ADS1X15 Arduino library repository) and CircuitPython. Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.

• This is great blue backlight LCD display. It is fantastic for Arduino based project. This LCD1602 LCD Display is very easy to interface with Arduino or Other Microcontrollers.
• This display overcomes the drawback of LCD 1602 Parallel LCD Display in which you’ll waste about 8 Pins on your Arduino for the display to get working. Luckily in this product, an I2C adapter is directly soldered right onto the pins of the display. So all you need to connect are the I2C pins, which shows a good library and little of coding.
• The I2C is a type of serial bus developed by Philips, which uses two bidirectional lines, called SDA (Serial Data Line) and SCL (Serial Clock Line). Both must be connected via pulled-up resistors. The usage voltages are standard as 5V and 3.3V.
• If you already have the I2C adapter soldered onto the board like in this product, the wiring is quite easy. You should usually have only four pins to hook up. VCC and GND of course. The LCD display works with 5 Volts. So we go for the 5V Pin.
• The values shown on the display can be either a simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles that the Arduino is performing.

Use the Ethernet library to write sketches which connect to the internet using the shield. The ethernet shield connects to an Arduino board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top.

The most recent revision of the board exposes the 1.0 pinout on rev 3 of the Arduino UNO board. This Ethernet Shield connects the UNO R3 board to the internet in mere minutes. Just plug this module onto your Arduino board, connect it to your network with an RJ45 cable (not included) and follow a few simple instructions to start controlling your world through the internet. allows you to connect your Arduino UNO 328 or MEGA 2650 1280 to a network or the internet AND retrieve or store files on a Micro SD Card!

The Ethernet Shield has a standard RJ-45 connection, with an integrated line transformer and Power over Ethernet enabled.
