LED Circuit Design - How to design LED circuits. How to calculate resistor size, how to protect LED, how long will a battery power a circuit, how to calculate resistor power rating, how to connect LED and much more.
HOW TO LIGHT A LED
My first circuit on the 5v breadboard
how to light a 3v blue led on a 5v power supply
voltage and current measurement test in this circuit
Clarification: it is preferable to always put a resistor in series with a LED even in the event of a power supply at the operating voltage of the LED to secure the LED, even if it works without resistance because a LED is driven by current and not by tension. So always put a resistor in series with an LED
This exercise proposes to study a display circuit of an active logic level in the low state with an LED. The resistor will then be calculated to limit the current in the LED to 10mA when on. The video particularly insists on the methodological aspects of this type of study.
