This is the first basic LED circuit I built many years ago in my school days and had given me immense pleasure to see glowing LED. For building this circuit you only need four things: LED- 1; Resistor ...

The above circuit is designed to drive a LED with 0.2A. This current rating is fixed by the Resistor R1 in the circuit. The formulae to determine the current is. I = Vref/R1 where, Vref is 1.25V for ...

We know that LED is a two terminal semiconductor device. It is used in most of the electronic circuits as a sign or visual representation to the normal human to know that circuit is working properly.

There are various applications of IR sensors such as TV remote controllers, burglar alarms and object counters. Here we have used IR sensors (infrared LEDs) to make an object-detection circuit and ...

Renesas Electronics announced the availability of the R2A20134EVB design support tool for the R2A20134. It comes mounted with the R2A20134, a high-efficiency LED driver IC for applications such as LED ...

In this paper, a fast-switching current-pulse driver for dimming controllers of light-emitting diode (LED) backlight applications is proposed. A pair of current switches, which is used for driving the ...
