The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...
Na jednej nóżce jest przylutowany rezystor, na drugiej zaś (prawdopodobnie) dioda zenera. Nie Zenera ale najpewniej zwykła dioda - zabezpiecza przed uszkodzeniem LED przy odwrotnym podłączaniu ...
I needed a pulsating light for a certain signaling. Voltage was 230V. So I decided to make a simple circuit, consisted of a LED diode, two capacitors, two resistors, a diac and a diode. Activity of ...
In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...
