Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

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 ...

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.

When designing a handheld device with a colour display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...

This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

Kids love building electric circuits, but connecting light bulbs to batteries with fiddly wires is tricky for young hands. Play dough and light-emitting diodes (LEDs) solve the problem beautifully.
