Resistor Calculator for electronics hobbyist

Resistor Calculator for measuring resistance

Resistor Calculator

A resistor calculator is a very useful tool for anyone working on electronic experiments or projects. It is easy to use and has a simple design.
To get resistance for Led voltage drop or your circuit resistance, you can use an online calculator or look up a formula. We can use it for voltage drops or led current limiting.

Online resistor calculator

It is a simple and easy-to-use online calculator instead of using formulas. It comes with different bands e.g.3 band, 4, 5, and 6 bands. The program calculates resistor values.

How to read resistance

We use it for any resistance size even though it is 330 ohm or 10k ohm. 
We used the first color for the first number; a second color is the 2nd number and the third one is the number of zero added to the value. The fourth color is its tolerance. It could be a grey, white, golden and silver color. The fifth color shows the temperature.

Arduino UNO Pinout (with Diagram)and board brief details

Arduino UNO Pinout and Board description Arduino Uno is an electronic experimental board. The Atmega328P Microcontroller is the main chip of the Arduino board. It is an open-source electronics platform, helpful to create electronics projects. I will explain the description of the  Arduino UNO Pins  and the board in the post.  Arduino Uno  is a standard board of the company, even though other boards e, g. micro, Nano, mega, Leonardo, 101. Due and Yen. Arduino also manufactured IoT (internet of things), Bluetooth, GSM/3G, Wi-Fi, and motion sensor boards. Arduino Uno board The Atmega328P Microcontroller is an 8bit with 32k byte internal flash memory. To program the main chip, a 16 MHz crystal is part of the board. The Arduino board requires only 5V DC to operate.                                                                       FIG-A Arduino Uno pins detail Arduino UNO board has analog/digital (PWM) pins. These pins could be GPIO or used for specific signals.   Vin Pin It uses Vin pin

788bs Led Matrix display interface with Arduino uno

788bs Led Matrix Pinout There are several types of led matrix Displays available in the market. We can differentiate it as per size and types of connection, e.g. 5x7, 8x8, common anode, and common cathode type. It comes in different single colors and RGB. But in this article, I will discuss 788bs as a common anode 8x8 red color matrix Modules. We use it in many electronics displaying items, e.g. electronics clocks. also for moving message displays, displaying games, etc. We use a dot matrix display with an Arduino UNO board directly, sometimes in projects. But for some projects, we use a max7219 chip or 74hc595 for dot matrix driver as required in our projects. 8x8 led Matrix Pinout details The 788bs led matrix modules used in various colors, but I specifically describe the red led matrix. It is very easy to Interface a led matrix with an Arduino board as compared to an RGB led display. If we look at a piece of the 8x8 dot matrix , it contains 16 pins in which 8 pins used for r

Getting started with arduino uno for led blinking

What is Arduino Uno? The Arduino Uno is an electronic board that has  the ATMEGA 328P microcontroller. It has analog and digital input/output pins. We use it in simple projects, e.g. led lights and also complicated robotics projects.  Let's  get started with  Arduino  to run our first program. As we use it with different machines e, g. Windows, Apple, Ubuntu, mobile, etc.  as usual Arduino programming is difficult for newbies, but if you get in touch with this Arduino tutorial, it could be helpful. Getting started with Arduino Here, I will discuss especially the Windows operating system and also a little another operating system. First, I will discuss how to interface with the Windows operating system.

Arduino Nano pins Tutorial with Diagram and Details

Arduino Nano pins details with schematic Arduino Nano comes in small size and has the same function as Arduino Duemilanove. Nano contains Atmega328P Microcontroller as the main chip. Nano uses a small jack for the DC power supply.  For the USB interface and power, it uses a mini USB type B cable.   It is an electronic experimental board and being small in size,  we could install it easily in our projects . It has more analog pins than Uno, so very helpful to create controlling type electronics projects . Arduino Nano Board Details If you look at the Nano board Arduino Nano Pins the Atmega328P micro-controller is the major component of the board. The board has four LEDs for different identification. For ON, RX for receiving data, TX for transmitting data, and L for loading the program. Arduino Nano pin Diagram Atmega328P Datasheet To learn Arduino Nano pin out it is necessary to understand the datasheet of the Atmega328P   Microcontroller . We can download the datasheet from the li
