Sometimes the most useful hacks are also the simplest ones. A case in point is the LED and resistor assembly that [Skippy] recently posted on his blog. The idea is to solder up some pre-made ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

One of the easiest soldering projects to do as a beginner is to solder a resistor to an LED. You can technically put the ...

Electronics are a hot topic today, and kids are eager to master the fundamentals of this interesting and important branch of technology. Here is a basic electronics course for kids that will teach and ...

Here, we have described a simple circuit named “Mains operated LED Lights” which you can easily made and install in your homes. This is a simple circuit named Mains Operated LED Lights which you can ...

Discover how to build a simple wireless power transfer system at home using readily available components like enameled copper wire, an LED, a 2N2222A transistor, and a 9V battery. This step-by-step ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

Driving multiple LEDs with one microprocessor GPIO pin is a well-known technique. Typically, designs perform this task by issuing pulse widths and clocks of differing durations and employing multiple ...
