The circuit was designed to create a handy logic probe that can show off the logic states for high, low and pulsing outputs with the use of CMOS 4001 integrated circuit. Logic Probe – a handheld probe ...

If you are looking to replace halogen bulbs with LEDs, combining a rectifier bridge and a current-controlled synchronous step-up/step-down converter creates a high power factor driver circuit, writes ...

Two strips of LEDs fading in a complementary manner, 9V Battery-operated portable unit This circuit operates two LED strips in pulsing mode, i.e. one LED strip goes from off state, lights up gradually ...
