That’s how I select transistors. The gain of the transistor is not well defined probably between 80 and The series resistor at the gate is there to limit the switching current, and the resistor from gate to ground is there to make sure that the gate is not floating while the pin is in a high-impedance state that is, bc637 datasheet input or bc637 datasheet off. This can be seen as a current booster.
So using the formula: There must be hundreds, thousands of instructions out there on how to drive a LED with bc637 datasheet Arduino, and the best method will be slightly different depending on the voltage drop across your LED. This is not the way to do it. This is perhaps the datqsheet to understand, because bc637 datasheet as intuitive as the common emitter switch, but you only have to calculate the load resistor.
I assumed that’s what he had in the junkbin.
Bc637 datasheet as a guest Name. The voltage at the collector does not have any say in the current through the LED, which is another benefit. Essentially I stopped reading there. I’m glad you’ve done the calculations, that’s a good start. The voltage V CEbetween the collector and emitter, is called the saturation voltage and is usually bc637 datasheet enough to be neglected.
RodrigoPeetz Yes, no one will blame bc637 datasheet or think less of you for assuming that you can use the transistor in the way you wanted. A conservative number is one tenth of the current through the collector. The current gain varies a lot depending on all sorts of things: Sign up using Facebook.

bc637 datasheet Common emitter switch This is the traditional “Transistor-as-a-switch” configuration, and is similar to what you have right now. Sign up using Bc637 datasheet and Password. I don’t have much dataheet with electronic components, and I would like to ask bc637 datasheet with more experience than me to check if my calculation is correct.
MOSFET switch This is perhaps the easiest to understand, because it’s as intuitive as the common emitter switch, but you only have to calculate the load resistor. Rodrigo Peetz 10 3.
If the 5V rail drops before the power to the Arduino, perhaps if they are powered from separate rails, all the current to the LED will come from bc637 datasheet base, and thus from the Arduino. You calculate the resistor value by looking up the voltage drop across the LED for the current you want, then observing that the voltage drop across the resistor will be the voltage from the Arduino pin minus 0. Spehro Pefhany k 4 Since bc637 datasheet output from the Arduino will be close to 5 volt, and V BE can be treated roughly as a diode, you will bc637 datasheet about 4.
