Tell us about yourself!
This circuit should be adaptable to higher current requirements as long as the transistor you choose will handle the current required by your leds. Just look for a transistor that will handle 10A(or other current reqts) and replace the generic NPN shown in the circuit. You’ll also want to ensure that you have current limiting resistors for your leds to avoid burning them up.
Depending on what you’re using it for, it should light a single led at 5V. You might need to change the values of the resistor but I have not tried 5V myself.
Glad this instructable is still working for people all these years later. Thanks for the comment.
Excellent work. I especially loved the idea for the lid. Easy vote for the contests.
