Resistor Calculator with Graphical Chart

Resistor Calculator for measuring resistance

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.

Resistor Calculator

Online resistor calculator

It is a simple and easy-to-use online resistor 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 a 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.
You can use this resistor calculator to find the correct value. And also easy access to use it anywhere.

Arduino sensors and modules list for Projects.

Arduino Sensors for Electronics Projects What is Sensor? A Sensor is a device used as the primary element that measures physical value and converts it into an electrical signal. Also, we can say that the sensor is a transducer. It measures temperature, distance, light, sound, etc. Sensors and actuators are widely used in Arduino projects. These sensors come with a kit or can be purchased separately. Some of them are compatible with Arduino Uno boards and also Raspberry Pi and other electronic modules. There are a lot of types of Arduino sensor kits available in the market. How many types of Arduino Sensors? There are a lot of sensors used in electronics projects , e.g. robotics cars, moving objects, flying drones, IoT(internet of things), sound and light operation, etc. Here is a list of 45 in 1 electronic sensor that comes with an Arduino sensors kit , and the details of their applications.

Led Matrix display interface with Arduino uno

LED matrix display pins with Arduino Interface    An 8x8 LED matrix is a grid of 64 LEDs arranged in 8 rows and 8 columns. It is commonly used in  various display and lighting applications, such as digital clocks, scrolling text displays, and graphical displays. Each LED can be controlled individually to create patterns, animations, or characters. I will introduce 788bs as a common anode red color 8x8 LED matrix display m odule. We use it in many electronics displaying items, e.g. electronic 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. led Matrix 8x8 Pin Configuration Each LED matrix can have a slightly different pin configuration, but a common arrangement is as follows: [LED Matrix] Pin 1 - Row 1 Pin 2 - Row 2 Pin 3 - Row 3 Pin 4 - Row 4 Pin 5 - Row 5 Pin 6 - Row 6 Pin
