This circuit can be used to test up to three LEDs at once, connected in series. You can easily increase that number by using a higher supply voltage. If you do so, you should allow 2.7 V for each ...
High-brightness LEDs, with independent delay and duration, find use in a visual-inspection application. This circuit is not complex, but it saved the day in an application involving visual inspection ...
Driven by 12 VAC, an MR16 LED lamp uses four diodes for the full bridge rectification and one diode for the freewheeling action. NXP's extremely low leakage 1 to 2 A, 20 to 40 V Schottky diodes in ...
