Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

Here is a simple and powerful LED circuit that can be operated directly from the AC 100 volt to AC 230 Volts mains supply. The circuit can be used as mains power locator or night lamp etc.. The ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

If you are seeking to get involved in electronics projects or are already doing so, you may still be getting accustomed to certain concepts – including the importance of LED resistors in circuit ...

Each LED is connected to one of the Arduino's digital output pins through a 220Ω resistor. A push button is connected to each input pin and uses the internal pull-up resistor feature of the Arduino.
