Electrical components Answered
Is there any components that set the minimum energy to pass through? When the energy is lower than the fix amount , no energy will be passing through.
I'm trying to make a project. I'll put a dynamo on my bicycle, and it will be connected to 3 LEDs. When I cycle in low speed, only one LED will light up. When I increase my speed to certain level, 2 LEDs will light up and if it passes a certain speed all LED will light up. Any idea?
