The AC03-CS series of axial cemented, leaded wirewound safety resistors offered by Vishay Intertechnology, Inc. is now ...

We spent some time with Corsair this week, and we got a hands on look at the new 'CONCEPT ORION' - which basically has special LEDs mounted in the glass - take a look at the effects you can get from ...

To build this DIY buzz wire game, you'd need an Arduino Nano, a 9V battery, two LEDs (red and green), a buzzer, a seven-segment LED display, a shift register for the display, and resistors for the ...

Example: circuit determines the LED has a forward voltage of 1.8v and you have 99v, 10mA set, it will do this: 99v-1.8v/0.01A and come up with 9720 ohms resistor. (10k would be the nearest common ...

In this step-by-step tutorial, we're diving into the world of electronics and microcontrollers to create a personalized 8 by 8 LED matrix that can be controlled using an Arduino board. I'm Chris, and ...

There are then other things that we put physically on the board that are new, one of them is an LED matrix. We managed to put 96 LEDs on the board itself and so we basically have a display which can ...

#define LED_BUILTIN 13. This indicates digital pin 13 on the Arduino's pins connector (also called a header). But at the same time LED_BUILTIN tells the Arduino to use the actual built-in LED on ...

A bi-color LED lights a different color depending on which direction the current is flowing. When the current to the Tortoise changes polarity, the LED will change color. Conveniently, you don’t even ...

You will need the Arduino board and USB cable, male-to-male jumper cables, a resistor (to make sure you don’t blow your LED), and LED lights of your choice (start with easy-to-spot red). Pay attention ...

The resistor is responsible for setting the upper limit of the current therefore limiting the overall brightness of the LEDs. The following table shows the values of the resistor that you should use ...

To make things a little easier to see, you can try connecting an LED bulb and a 250Ω resistor between D13 and GND. Do this on a breadboard to make it easier and make sure to disconnect the Arduino ...
