Arduino boards power supply

Hello People. This article is about Arduino boards power supply. There are several power pins on an arduino board.

The different power pins are as follows:

  • VIN. This pin can take input voltage to the Arduino board when it’s using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
  • 5V. This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 – 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don’t advise it.
  • 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.
  • GND. Ground pins.

The Arduino Uno can be powered via the USB connection or with an external power supply. The power source is selected automatically.

External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board’s power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector.

The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.

Arduino boards power supply


There are mainly three methods of supplying power to arduino board. The Vin, 5V, 3.3V, and GND pins are Arduino power pins. You can use the Vin pin to Power your Arduino with an unregulated 7 to 12-volt power source. Like a 9V battery or a wall adapter that is in the range of 7 to 12 volts. Alternatively, you can power your Arduino through the 5V pin with an external regulated 5V power supply. It can be a wall adapter that gives out constant 5V or a DC-DC converter that is connected to a battery or a set of batteries. You can use both the 5V pin and the 3.3V pin to provide power to modules that are connected to the Arduino. But you can’t use the 3.3V pin to power your Arduino Uno/Nano.

Arduino UNO Pins explained

Hello People. This article is titled Arduino UNO Pins explained. Arduino Uno is one of the most popular microcontroller. It has the development board based on 8-bit ATmega328P microcontroller. In addition to ATmega328P MCU IC, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc. to support the microcontroller.

Arduino Uno has 14 digital input/output pins (6 of them can be used as PWM outputs), 6 analog input pins, a USB connection, A Power barrel jack, an ICSP header and a reset button.

How to use Arduino UNO Pins

As explained above, the 14 digital input/output pins can be used as input or output pins by using pinMode(), digitalRead() and digitalWrite() functions in arduino programming. Each pin operates at 5V and can provide or receive a maximum of 40mA current, and has an internal pull-up resistor of 20-50 KOhms which are disconnected by default.  Out of these 14 pins, some pins have specific functions as listed below:

  • Serial Pins 0 (Rx) and 1 (Tx): Rx and Tx pins are used to receive and transmit TTL serial data. They are connected with the corresponding ATmega328P USB to TTL serial chip.
  • External Interrupt Pins 2 and 3: These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.
  • PWM Pins 3, 5, 6, 9 and 11: These pins provide an 8-bit PWM output by using analogWrite() function.
  • SPI Pins 10 (SS), 11 (MOSI), 12 (MISO) and 13 (SCK): These pins are used for SPI communication.
  • In-built LED Pin 13: This pin is connected with an built-in LED, when pin 13 is HIGH – LED is on and when pin 13 is LOW, its off.
Arduino UNO Pins explained

Along with 14 Digital pins, there are 6 analog input pins. Each of them provide 10 bits of resolution, i.e. 1024 different values. They measure from 0 to 5 volts but this limit can be increased by using AREF pin with analog Reference() function.  

  • Analog pin 4 (SDA) and pin 5 (SCA) also used for TWI communication using Wire library.

Arduino Uno has two other pins as explained below:

  • AREF: Used to provide reference voltage for analog inputs with analogReference() function.
  • Reset Pin: Making this pin LOW, resets the microcontroller.

Printed Circuit Board designing business

Hello People. This article discusses about Printed Circuit Board designing business. Designing PCB circuit is a complicated process and it requires an advanced skillset. In the highly-competitive field of printed circuit board design, assembly, and fabrication, you must understand that you must go the extra mile in order to win a customer’s business.

Important steps in PCB design process

  • System & Board Level Architecture Specification
  • Engineering Design Specification
  • Component Selection
  • Component Obsolescence & Planning
  • Symbol Creation
  • Schematic Drawing/Capture
  • Timing Analysis
  • Netlist Generation
  • BOM Generation
  • Tools: (OrCAD, Concept HDL Altium, PADs, Expedition)
Printed Circuit Board designing business

To better have an understanding about the PCB designing as well as manufacturing process, let us look at the process in detail. From PCB schematic design and PCB board layout to testing, validation, and certification, here is the full cycle of the PCB design process. See the detailed breakdown of printed circuit board design and manufacturing.

Preparing a technical specification

Preparing a project specification is an important part of a custom PCB design service. It may include technical requirements, block diagrams, deliverables, assumptions, a preliminary bill of materials (BOM) and BOM costs, tools and technologies specified for the project development. The specification allows PCB designers to stay on the same page with customers and meet their expectations.

Schematic design

The process of PCB board design always starts with schematics. A schematic or a circuit diagram conveys the electrical connection between different electrical components like integrated circuits (ICs) and discrete components. To deliver this PCB design service, PCB designers use professional CAD software, such as Fritzing, Altium Designer etc to define modules and design the connectivity between different components.

PCB layout

Once the schematic is imported to the PCB layout, PCB designers place components on the board and route the traces. They take into consideration the number of required layers and the dimensions of components that may be limited by the size of the housing. Within the PCB layout services, they analyze signal integrity and evaluate electrical limitations to ensure the safety of the board level architecture. For a complex layout, they include various simulations into their custom circuit board design services. PCB specialists arrange proper conductor routing, which is the primary factor affecting the price of PCB manufacturing. They run DFM/DFA analysis to minimize PCB design revisions, cut development costs, and reduce time to market.

PCB fabrication and testing

Once PCB design layout is approved for production, they export it into the format the manufacturer supports. They prepare a bill of materials (BOM) and Gerber files that describe design requirements for each image of a circuit board. Manufacturers use this documentation as a reference for board fabrication and PCB assembly. For certain projects, they also create a 3D model of a PCB to make sure it fits the housing. Testing is essential for both PCB layout design services and the fabrication stage. They provide the manufacturer with the data and software necessary to perform an electrical and impedance test. After the prototypes are manufactured, they test them in-house.

Mass production

After the prototype validation, they prepare the files for mass production and assist the customer throughout the manufacturing process. They arrange special software, hardware, and testing procedures. Using them, the manufacturer can test each PCB at the factory.

Technical support

Upon completion of the project, PCB manufacturers create a full document package that comprises BOM and Gerber files, 3D models, and technical manuals. In addition, they set a warranty period for PCB design services. During this period, they fix bugs and provide other technical support covered by the warranty. After the warranty period ends, they stay in touch with customers and can consult them when needed.

Node Red and its application

Hello People. This article explains you What is Node Red and its application. Node-RED is a programming tool for wiring together hardware devices, APIs and online services. At the core of Node-RED is Node.js, which (as you know) is a JavaScript runtime that has an active community.

Because of its ease of use, node-red is ideally suited for building IOT and Home control dashboards and automations as well as many other applications.

Node-Red IOT and Home Automation

Industrial IOT and home automation applications will generally use one or more of the following protocols.

  • MQTT
  • HTTP

Nodes for these protocols are part of the core nodes.

Node Red and its application

Various platforms

Node-RED can be used on various platforms. That’s because Node-RED itself is a Node.js application. If you have a runtime environment for Node.js, you can run it. It is mostly used on Edge devices, cloud services, and in embedded formats.

The perfect starting point for Node-RED applications is the ADAM-6700 series modules that come complete with Node-RED installed, plus onboard I/O and an extensive built in library to assist with utilising the ADAMs functions. Other functions and sample code can be added from other Node-RED users or by building your own applications and importing them into other projects you may do in the future.

An example of an application using Node-RED could be for a specific signalling arrangement for alarm monitoring. This could include analogue, serial, or ethernet devices all covered in a single unit that provides email and SMS support via a network. It could also include a dashboard on the local network with raw data that the alarms are based on, with logging on board using an SD Card.

A router using Node-RED can provide monitoring of 4G signal reception, alerts for signal loss, network performance and data usage just to name a few. As with modern equipment, Node-RED can provide benefits to make products intuitive to the user’s requirements whether for additional features or just using the dashboard function for service acknowledgement or fault reporting.
