Topic: Add a battery to my transistor (Read 211 times) previous topic - next topic


Hello, i need help, i want to connect the battery to the transistor because i want to increase the voltage that the led receive but i don't know why it doesn't work.


Here is the tinkercad circuit, thanks for the help.


Link doesn't work - requires login. Please post image of your circuit here.

Also from your description I don't understand what you're even to try to do - nor where an Arduino or related device would come in play.
Quality of answers is related to the quality of questions. Good questions will get good answers. Useless answers are a sign of a poor question.


LED' drop a constant voltage across them ( in the range 1-2v), the current through them is limited by a series resistor .  I'm guess you want to put more current through your led  than can be provided by an Arduino pin, so you want to
Use a transistor .
