Quick question, hoping someone can point me in the right direction.
I need to light up 3 x 3.3V 20mA LEDs using a 5V power source. I need to turn these LEDs (in series) on and off via a small hall effect sensor THIS ONE. That sensor says it can only output 10ma which my LED circuit draws 60. I have THIS transistor which I was hoping to use to supply the 60 mA of current. When I apply 5V to my circuit the LEDs glow dimly as about 1.5-2.5V "sneaks" through my transistor and halleffect sensor before I use a magnet to "open up" the full amount of power.
Hopefully this makes sense? Its one of my first circuits, any advice would be greatly appreciated! Thanks!
