In this tutorial I am going to create a Police Light themed LED Flashing circuit using the 555 timer IC. My 5-year old son asked me to create a Police Car like flashing light that he can put on top of ...

555 timer IC is an electronic component that we use in many electronic projects. It is called a timer because it can be used to control the time for which an electronic device stays on or off. The 555 ...

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 ...

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 In this ...

I was following the Blinking LED Circuit tutorial from the docs but I got stuck after going through all the steps.

Discover the step-by-step process of creating a powerful music reactive LED strip circuit in this comprehensive tutorial.

An LED dimmer circuit adjusts the brightness of LED strips, serving both as an energy-saving tool and a method to create aesthetic lighting. Call bells, designed to draw attention, are commonly used ...

This is a very simple LED dimmer circuit which has 2 transistors, 1 resistor and 2 potentiometers. Typical segment displays LEDs consume around 25 mA for each segment and should be limited to this ...

It seems deceptively simple to establish galvanic isolation with the help of optocouplers between circuits that operate at different ground potentials. Optocouplers draw power from the isolated ...

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.
