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 ...

I love all about electronics, circuit diagrams and crazy projects that can help us achieve almost everything our mind can conceive. I created this website and I want to invite you to participate in ...

Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

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 ...
